    Multifrequency Astrophysics (A pillar of an interdisciplinary approach for the knowledge of the physics of our Universe) ∗† Franco Giovannelli PoS(MULTIF2017)001 INAF - Istituto di Astrofisica e Planetologia Spaziali, Via del Fosso del Cavaliere, 100, 00133 Roma, Italy E-mail: [email protected] Lola Sabau-Graziati INTA- Dpt. Cargas Utiles y Ciencias del Espacio, C/ra de Ajalvir, Km 4 - E28850 Torrejón de Ardoz, Madrid, Spain E-mail: [email protected] We will discuss the importance of the "Multifrequency Astrophysics" as a pillar of an interdis- ciplinary approach for the knowledge of the physics of our Universe. Indeed, as largely demon- strated in the last decades, only with the multifrequency observations of cosmic sources it is possible to get near the whole behaviour of a source and then to approach the physics governing the phenomena that originate such a behaviour. In spite of this, a multidisciplinary approach in the study of each kind of phenomenon occurring in each kind of cosmic source is even more pow- erful than a simple "astrophysical approach". A clear example of a multidisciplinary approach is that of "The Bridge between the Big Bang and Biology". This bridge can be described by using the competences of astrophysicists, planetary physicists, atmospheric physicists, geophysicists, volcanologists, biophysicists, biochemists, and astrobiophysicists. The unification of such com- petences can provide the intellectual framework that will better enable an understanding of the physics governing the formation and structure of cosmic objects, apparently uncorrelated with one another, that on the contrary constitute the steps necessary for life (e.g. Giovannelli, 2001).

  • Tetrahedral Hydrocarbon Nanoparticles in Space: X-Ray Spectra
    Mon. Not. R. Astron. Soc. 000, 1–7 (2018) Printed 15 October 2018 (MN LATEX style file v2.2) Tetrahedral hydrocarbon nanoparticles in space: X-ray spectra G. Bilalbegovic´1, A. Maksimovic´2, L. A. Valencic3;4 1Department of Physics, Faculty of Science, University of Zagreb, Bijenickaˇ cesta 32, 10000 Zagreb, Croatia 2Center of Excellence for Advanced Materials and Sensing Devices, Rudjer Boskoviˇ c´ Institute, Bijenickaˇ cesta 54, 10000 Zagreb, Croatia 3NASA Goddard Space Flight Center, Greenbelt, MD 20771, USA 4The Johns Hopkins University, Department of Physics & Astronomy, 366 Bloomberg Center, 3400 N. Charles St., Baltimore, MD 21218, USA 15 October 2018 ABSTRACT It has been proposed, or confirmed, that diamond nanoparticles exist in various environ- ments in space: close to active galactic nuclei, in the vicinity of supernovae and pulsars, in the interior of several planets in the Solar system, in carbon planets and other exoplanets, carbon- rich stars, meteorites, in X-ray active Herbig Ae/Be stars, and in the interstellar medium. Using density functional theory methods we calculate the carbon K-edge X-ray absorption spectrum of two large tetrahedral nanodiamonds: C26H32 and C51H52. We also study and test our methods on the astrophysical molecule CH4, the smallest C-H tetrahedral structure. A possible detection of nanodiamonds from X-ray spectra by future telescopes, such as the project Arcus, is proposed. Simulated spectra of the diffuse interstellar medium using Cyg X-2 as a source show that nanodiamonds studied in this work can be detected by Arcus, a high resolution X-ray spectrometer mission selected by NASA for a Phase A concept study.

  • The Loopy UV Line Profiles of RU Lupi: Accretion, Outflows, and Fluorescence
    submitted to AJ The loopy UV line profiles of RU Lupi: accretion, outflows, and fluorescence Gregory J. Herczeg1, Frederick M. Walter2, Jeffrey L. Linsky1, G¨osta F. Gahm3, David R. Ardila4, Alexander Brown5, Christopher M. Johns-Krull6, Michal Simon2, Jeff A. Valenti7 ABSTRACT We present far-ultraviolet spectra of the classical T Tauri star RU Lupi covering the 912–1710 A˚ spectral range, as observed by the HST /STIS and FUSE satellites. We use these spectra, which are rich in emission and absorption lines, to probe both the accreting and outflowing gas. Absorption in the Lyα profile constrains the extinction to AV ∼ 0.07 mag, which we confirm with other diagnostics. We estimate a mass −8 −1 accretion rate of (5 ± 2) × 10 M⊙ yr using the optical-NUV accretion continuum. The accreting gas is also detected in bright, broad lines of C IV, Si IV, and N V, which all show complex structures across the line profile. Many other emission lines, including those of H2 and Fe II, are pumped by Lyα. RU Lupi’s spectrum varies significantly in the FUV; our STIS observations occurred when RU Lupi was brighter than several other observations in the FUV, possibly due to a high mass accretion rate. Subject headings: accretion, accretion disks — circumstellar matter — line: iden- tification — stars: individual (RU Lupi) — stars: pre-main sequence — ultraviolet: stars 1.

In dieser Doktorarbeit wird hochenergetische Strahlung von Sternen untersucht, die noch aktiv Material von ihrer Scheibe akkretieren, aber nicht mehr von einer Staub- und Gash¨ulle verdeckt sind. In dieser Phase nennt man Sterne der Spektraltypen A und B Herbig Ae/Be (HAeBe) Sterne, alle sp¨ateren Sterne heißen klassische T Tauri Sterne (CTTS); eigentlich werden beide Typen ¨uber spektroskopische Merkmale definiert, aber diese fallen mit den hier genannten Entwicklungsstadien zusammen. In dieser Arbeit werden CTTS und HAeBes mit hochaufl¨osender Spektroskopie im R¨ontgen- und UV-Bereich untersucht und Simulationen f¨ur diese Stadien gezeigt. F¨ur zwei Sterne werden R¨ontgenspektren reduziert und vorgestellt: Der CTTS V4046 Sgr wurde mit Chandra f¨ur 100 ks beobachtet. Die Lichtkurve dieser Beobachtung zeigt einen Flare und die Triplets der He Isosequenz (Si xiii, Ne ix und O vii) deuten auf hohe Dichten im emittierenden Plasma hin.

I present an overview of some observations of young and active solar- University like stars with non-solar-like characteristics. I ask whether the solar anal- ogy can be extrapolated to explain very active stars without violating 2003 simple geometrical constraints.

It is, rather, a set of variations on a theme: the solar analogy, as a guide to the interpretation of the coronae and chromospheres of the most active Stars, stars, needs to be reconsidered. You may alternatively consider this an extended ol introduction and overview, designed to set the scene for the contributed papers Co in this session. To that end, making no pretense of being complete or unbiased, on I present a series of observations focussed on non-solar-like properties in active cool stars, intended to provoke discussion. Our paradigm has long been that stellar magnetic activity is just like solar magnetic activity, only ever-so-much-more-so.

Low and to the right is the great red pulsating supergiant, Betelgeuse (alpha Orionis). Recently acquiring fame for being the first star to have its atmosphere directly imaged (shown below), alpha Orionis has captivated observers' attention for centuries. At minimum brightness, as in 1927 and 1941, its magnitude may drop below 1.2.
