Salamaa aSpace Science and Astrobiology Division, NASA Ames Research Center, Moffett Field, California, USA Contact: [email protected] An overview of the current status and critical needs in astrochemistry will be presented. The discipline of Astrochemistry is an overlap of astronomy and chemistry and is com- monly defined as the study of molecules in the Universe. Molecules are one of the vital ingredients of our Universe and the understanding of their interaction with photons and cosmic ray radiation in space is key to our understanding of the evolution of the Universe. Astrochemistry sheds light on the chemistry of interstellar clouds and the formation of stars and planets and applies to both the Solar System and the interstellar medium. As a result, Astrochemistry includes gas-phase chemistry, ices, surface chemistry, photochem- istry, isotope chemistry and plasma chemistry among others. Emphasis will be given in this presentation to the major role that astrochemistry plays in the optimization of the science return from space missions. 6 Exploring the formation of complex organic molecules in solar-type protostars with ALMA A. Coutensa, J. K. Jørgensenb, H. S. P. M¨ullerc and the PILS team aLaboratoire d'Astrophysique de Bordeaux, Univ. Bordeaux, CNRS, France bCentre for Star and Planet Formation, Niels Bohr Institute & Natural History Museum of Denmark, University of Copenhagen, Denmark cI. Physikalisches Institut, Universit¨atzu K¨oln,Germany Contact: [email protected] Complex organic molecules are detected in a large variety of astrophysical environments. They are particularly abundant in the warm inner regions of protostars, where planets, comets and asteroids are expected to form. These molecules may survive during the star formation process and be incorporated into asteroids and comets, which could deliver them to planetary embryos through impacts and thus favor the emergence of life. It is, therefore, important to understand how these molecules form and how they evolve towards more complexity. Thanks to the high spatial resolution and high sensitivity of the interferometers ALMA and NOEMA, new opportunities were offered to astronomers to characterize the molecular complexity in low-mass star-forming regions. In particular, several new detections of complex molecules were obtained in the framework of the PILS program, an unbiased spectral survey of the solar-type protostar IRAS 16293-2422 with ALMA (e.g., Jørgensen et al. 2016, Lykke et al. 2017, Ligterink et al. 2017). Isotopologues of several complex molecules (D, 15N, 13C) were also detected for the first time in the interstellar medium (e.g., Coutens et al. 2016, 2018, Jørgensen et al. 2016), which helps constrain formation pathways of molecules. In this talk, I will especially mention the recent detection of cyanamide (NH2CN) and its deuterated form (Coutens et al. 2018). I will discuss what it teaches us regarding its formation in connection with formamide (NH2CHO) and why it would be interesting to search for its 15N isotopologues.

Skouterisa, V. Baronea, N. Balucanib, C. Puzzarinic, C. Ceccarellid, F. Vazartd aScuola Normale Superiore, Pisa; bUniversit`adegli Studi di Perugia; cUniversity of Bologna; dInstitut de Planetologie et d'Astrophysique de Grenoble The search for the origin of prebiotic species in space is an ongoing discipline of enormous interest in astrochemistry and in the study of the origin of life. It has been shown that essentially all biological macromolecules can be envisaged as forming from relatively simple precursors, such as formamide, which are relatively common in interstellar clouds (ISCs). Yet, the formation of formamide and other simple prebiotic molecules is difficult to explain in the harsh environments of ISCs, where very low temperatures and number densities prevail. Dedicated experimental approaches have been developed to address prebiotic molecules formation mechanisms, in which either the low temperature or the low number density regimes are reproduced. Nevertheless, for some specific cases, the experimental techniques are difficult (if not impossible) to apply. For this reason, we have started a systematic investigation by using high-level electronic structure calculations coupled with kinetics cal- culations to elucidate the mechanisms of formation of complex organic molecules (COMs) of prebiotic interest which cannot be addressed experimentally. The mechanisms dis- cussed take place exclusively in the gas phase, starting from reactants which are rela- tively abundant in ISCs. The species discussed include formamide (a possible precursor of both aminoacids and nucleobases), glycolaldehyde (a prototype for sugars), acetic acid (a possible precursor of glycine) and formic acid.

  • Interferometric Observations of Large Biologically Interesting Interstellar and Cometary Molecules
    SPECIAL FEATURE: PERSPECTIVE Interferometric observations of large biologically interesting interstellar and cometary molecules Lewis E. Snyder* Department of Astronomy, University of Illinois, 1002 West Green Street, Urbana, IL 61801 Edited by William Klemperer, Harvard University, Cambridge, MA, and approved May 26, 2006 (received for review March 3, 2006) Interferometric observations of high-mass regions in interstellar molecular clouds have revealed hot molecular cores that have sub- stantial column densities of large, partly hydrogen-saturated molecules. Many of these molecules are of interest to biology and thus are labeled ‘‘biomolecules.’’ Because the clouds containing these molecules provide the material for star formation, they may provide insight into presolar nebular chemistry, and the biomolecules may provide information about the potential of the associated inter- stellar chemistry for seeding newly formed planets with prebiotic organic chemistry. In this overview, events are outlined that led to the current interferometric array observations. Clues that connect this interstellar hot core chemistry to the solar system can be found in the cometary detection of methyl formate and the interferometric maps of cometary methanol. Major obstacles to under- standing hot core chemistry remain because chemical models are not well developed and interferometric observations have not been very sensitive. Differentiation in the molecular isomers glycolaldehdye, methyl formate, and acetic acid has been observed, but not explained. The extended source structure for certain sugars, aldehydes, and alcohols may require nonthermal formation mechanisms such as shock heating of grains. Major advances in understanding the formation chemistry of hot core species can come from obser- vations with the next generation of sensitive, high-resolution arrays.

To aid the identification in these narrow line sources, four centimetre-wave rotational transitions (two in the previously reported Ka = 0 ladder and two new ones in the Ka = 1 ladder) and 23 transitions in the millimetre band between 96 and 272 GHz were measured in high-resolution laboratory spectra. Ten spectroscopic constants in a standard asymmetric top Hamiltonian allow the main transitions of astronomical interest −1 in the Ka ≤ 3 rotational ladders to be calculated to within 0.1 km s in radial velocity up to 400 GHz.

  • Arxiv:1802.10216V1 [Physics.Chem-Ph] 28 Feb 2018 They Play an Important Role in Their Spectroscopic Characteriza- Not Been Systematically Investigated
    Bound and continuum-embedded states of cyanopolyyne anions† Wojciech Skomorowski, Sahil Gulania, and Anna I. Krylova Cyanopolyyne anions were among the first anions discovered in the interstellar medium. The discovery have raised questions about routes of formation of these anions in space. Some of the proposed mechanisms assumed that anionic excited electronic states, either metastable or weakly bound, play a key role in the formation process. Verification of this hypothesis requires detailed knowledge of the electronic states of the anions. Here we investigate bound and continuum states of four cyanopolyyne anions, CN−,C3N−,C5N−, and C7N−, by means of ab initio calculations. We employ the equation-of-motion coupled-cluster method augmented with complex absorbing potential. We predict that already in CN−, the smallest anion in the family, there are several low-lying metastable states of both singlet and triplet spin symmetry. These states, identified as shape resonances, are located between 6.3–8.5 eV above the ground state of the anion (or 2.3–4.5 eV above the ground state of the parent radical) and have widths of a few tenths of eV up to 1 eV. We analyze the identified resonances in terms of leading molecular orbital contributions and Dyson orbitals. As the carbon chain length increases in the C2n+1N− series, these resonances gradually become stabilized and eventually turn into stable valence bound states. The trends in energies of the transitions leading to both resonance and bound excited states can be rationalized by means of the Hückel model. Apart from valence excited states, some of the cyanopolyynes can also support dipole bound states and dipole stabilized resonances, owing to a large dipole moment of the parent radicals in the lowest 2S+ state.

  • Laboratory Experiments of Titan Tholins Formed by Photochemistry of Cyanopolyynes
    BIO Web of Conferences 2, 01005 (2014) DOI: 10.1051/bioconf/20140201005 C Owned by the authors, published by EDP Sciences, 2014 Laboratory Experiments of Titan Tholins formed by Photochemistry of Cyanopolyynes I. Couturier-Tamburelli1, I. N. Piétri1 1Aix Marseille Université, Laboratoire PIIM, UMR 6633, 13397 Marseille cedex 20 France. Tholins are complex organic materials produced by irradiation of several carbon and nitrogen rich atmosphere. It has been proposed that Tholins could have played an important role in the origin of life on Earth [1]. We investigate the formation of polymer (Tholins) from the photolysis of dicyanoacetylene. As of today, nitriles molecules have been identified in Titan atmosphere. Among these nitriles, the cyanopolyynes (HCnN) are very important since they are the essential constituents in building block amino acids. It is known that a rich phochemistry takes place in the Titan aerosols, and contributes to the evolution of molecular diversity in this atmosphere. These compounds evolve through polymerization processes in aerosol particles, which grow by coagulation and rain down to the surface of Titan containing water ice. We present photochemical processes of larger cyanopolyyne formation from small precursor molecules submitted to long wavelength photons. Under UV irradiation cyanopolyynes are known to induce izomerization process (figure 1) [2] and formation of longer cyanopolyynes [3]. Figure 1: Izomerisation process of cyanopolyynes. We provide the photochemical processes of Titan Tholins formation (figure 2) from cyanopolyyne precursor molecules submitted to long wavelength photons. Such photons penetrate down into the stratosphere and troposphere (figure 3). The photoreactivity of the cyanopolyynes with other Titan molecules are also presented.

Pihlstrom,¨ UNM; Chris Salter, NRAO. Abstract: Heavy molecule spectroscopy is a developing subject, with new results from both the terrestrial laboratory and astronomical discovery in the 0.5-10 GHz range where heavy molecule spectral lines are easily distinguished. Dense clouds in space contain an astonishingly rich collection of both familiar and exotic molecules in various states of ionization and excitation. It means that there are many more ways to build large organic molecules in these environments than have been previously explored. These add to the number of paths available for making the complex organic molecules and other large molecular species that may be the precursors to life. 1 1 Heavy Molecules Most known interstellar molecules are small and have their lowest rotational transitions in the millimeter wavelength range (e.g., McGuire 2018a). Heavier molecules have their lowest rota- tional transitions in the microwave range and are especially prominent at the low temperatures that characterize many dense molecular clouds.

  • Chemical Modeling of Interstellar Molecules in Dense Cores
    Chemical Modeling of Interstellar Molecules in Dense Cores Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Donghui Quan, M.S. Graduate Program in Chemical Physics The Ohio State University 2009 Dissertation Committee: Professor Eric Herbst, Advisor Professor Frank C. De Lucia Professor Anil K. Pradhan Copyright by Donghui Quan 2009 ii Abstract There are billions of stars in our galaxy, the Milky Way Galaxy. In between the stars is where the so-called “interstellar medium” locates. The majority of the mass of interstellar medium is clumped into interstellar clouds, in which cold and hot dense cores exist. Despite of the extremely low densities and low temperatures of the dense cores, over one hundred molecules have been found in these sources. This makes the field of astrochemistry vivid. Chemical modeling plays very important roles to understand the mechanism of formation and destruction of interstellar molecules. In this thesis, chemical kinetics models of different types were applied: in Chapter 4, pure gas phase models were used for seven newly detected or confirmed molecules by the Green Bank Telescope; in Chapter 5, the potential reason of non-detection of O2 was explored; in Chapter 6, the mysterious behavior of CHNO and CHNS isomers were studied by gas-grain models. In addition, effects of varying rate coefficients to the models are also discussed in Chapter 3 and 7. ii Dedication Dedicated to my parents Quan He (全和), Li Lianxiang (李廉祥) and my wife Wang Jing (王璟) iii Acknowledgements First of all, I would like to thank my advisor, Professor Eric Herbst, who has always been supportive in all means: a mentor in my graduate study, a guide in astrochemical research, and a kind “father” in the life.

These molecules were detected through several emission lines in a deep Q-band line survey of TMC-1 carried out with the Yebes 40m telescope. These observations reveal that the cyanopolyyne peak of TMC-1, which is a prototype of a cold dark cloud rich in carbon chains, also contains O-bearing complex organic molecules such as HCOOCH3 and CH3OCH3, which have previously been seen in a handful of cold interstellar clouds. In addition, this is the first secure detection of C2H3OH in space and the first time that C2H3CHO and C2H3OH have been detected in a cold environment, adding new pieces to the puzzle of complex organic molecules in cold sources. We derive 11 −2 12 −2 12 −2 12 −2 column densities of (2.2 ± 0.3) × 10 cm , (2.5 ± 0.5) × 10 cm , (1.1 ± 0.2) × 10 cm , and (2.5 ± 0.7) × 10 cm for C2H3CHO, C2H3OH, HCOOCH3, and CH3OCH3, respectively.

Sternberg LISA, CNRS & Universités Paris 7 & Paris12, 61 Avenue Général de Gaulle, F-94000 Créteil, France ABSTRACT Since the first Voyager data , Titan, the largest satellite of Saturn and only satellite in the solar system having a dense atmosphere, became one of the key planetary bodies for astrobiological studies, due to: i) its many analogies with planet Earth, in spite of much lower temperatures, ii) the already well observed presence of an active organic chemistry, involving several of the key compounds of prebiotic chemistry, in the gas phase but also assumed to occur in the solid phase through the haze particles. And the potential development of a prebiotic chemistry in liquid water, with a possible water ocean in its internal structure, and the possible episodic formation of small liquid water bodies for short but not negligible time duration at the surface (from the melting of surface water ice by impact). Iii) the resulting possibility that life may have emerged on or in Titan and may have been able to adapt and to persist. These aspects are examined with some of the associated questions on the basis of the already available Cassini-Huygens data. Keywords: astrobiology, Cassini-Huygens, prebiotic chemistry, primitive Earth, Tholins, Titan 1. INTRODUCTION Beyond the Earth, which is still the only planetary body where we are sure that life is present, there are many other bodies of astrobiological interest in the solar system.

In this paper, we present a model to predict and explain the observed gradients in deuterium fractiona- tion and molecular abundance along the TMC-1 ridge. In TMC-1, gradients in the level of deuterium fractionation + are observed for all the molecular species for which the measurement has been made; HCO ,HC3N, C3H2 and HNC. The model is based on the assumption that the chemical evolution of the TMC-1 ridge has been affected by Alfv´en waves. The structure of the model and its comparison with observations are discussed. We find that the model qualitatively and somewhat quantitatively reproduces the observations of the aforementioned molec- ular species. We present predictions of the fractionation gradients along the TMC-1 ridge for other molecules of observational interest. Key words.
