    Space Sci Rev (2020) 216:100 https://doi.org/10.1007/s11214-020-00719-1 A Review of Possible Planetary Atmospheres in the TRAPPIST-1 System Martin Turbet1 · Emeline Bolmont1 · Vincent Bourrier1 · Brice-Olivier Demory2 · Jérémy Leconte3 · James Owen4 · Eric T. Wolf5 Received: 14 January 2020 / Accepted: 4 July 2020 / Published online: 23 July 2020 © The Author(s) 2020 Abstract TRAPPIST-1 is a fantastic nearby (∼39.14 light years) planetary system made of at least seven transiting terrestrial-size, terrestrial-mass planets all receiving a moderate amount of irradiation. To date, this is the most observationally favourable system of po- tentially habitable planets known to exist. Since the announcement of the discovery of the TRAPPIST-1 planetary system in 2016, a growing number of techniques and approaches have been used and proposed to characterize its true nature. Here we have compiled a state- of-the-art overview of all the observational and theoretical constraints that have been ob- tained so far using these techniques and approaches. The goal is to get a better understanding of whether or not TRAPPIST-1 planets can have atmospheres, and if so, what they are made of. For this, we surveyed the literature on TRAPPIST-1 about topics as broad as irradiation environment, planet formation and migration, orbital stability, effects of tides and Transit Timing Variations, transit observations, stellar contamination, density measurements, and numerical climate and escape models. Each of these topics adds a brick to our understand- ing of the likely—or on the contrary unlikely—atmospheres of the seven known planets of the system.

Called “Cool Stars, Stellar Systems, and the Sun,” the meeting empha- sized the solar stellar connection and focused discussion on “several topics … in which the similarity is manifest: the structures of chromospheres and coronae, stellar activity, and the phenomena of mass loss,” according to the preface of the resulting, “Special Report of the Smithsonian Astrophysical Observatory.” We could easily have chosen the same topics for this meeting. Over the summer of 1980, the group met again in Bonas, France and then back in Cambridge in 1981. Nearly 40 years on, I am comfortable saying these workshops have evolved to be the premier conference series for cool star research. Cool Stars has been held largely biennially, alternating between North America and Europe. Over that time, the field of stellar astro- physics has been upended several times, first by results from Hubble, then ROSAT, then Keck and other large aperture ground-based adaptive optics telescopes.

  • Spectra As Windows Into Exoplanet Atmospheres
    SPECIAL FEATURE: PERSPECTIVE PERSPECTIVE SPECIAL FEATURE: Spectra as windows into exoplanet atmospheres Adam S. Burrows1 Department of Astrophysical Sciences, Princeton University, Princeton, NJ 08544 Edited by Neta A. Bahcall, Princeton University, Princeton, NJ, and approved December 2, 2013 (received for review April 11, 2013) Understanding a planet’s atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability. This requirement puts a premium on obtaining spectra and developing credible interpretative tools with which to retrieve vital planetary information. However, for exoplanets, these twin goals are far from being realized. In this paper, I provide a personal perspective on exoplanet theory and remote sensing via photometry and low-resolution spectroscopy. Although not a review in any sense, this paper highlights the limitations in our knowledge of compositions, thermal profiles, and the effects of stellar irradiation, focusing on, but not restricted to, transiting giant planets. I suggest that the true function of the recent past of exoplanet atmospheric research has been not to constrain planet properties for all time, but to train a new generation of scientists who, by rapid trial and error, are fast establishing a solid future foundation for a robust science of exoplanets. planetary science | characterization The study of exoplanets has increased expo- by no means commensurate with the effort exoplanetology, and this expectation is in part nentially since 1995, a trend that in the short expended. true.

  • Similarities in Body Size Distributions of Small-Bodied Flying Vertebrates
    Evolutionary Ecology Research, 2004, 6: 783–797 Similarities in body size distributions of small-bodied flying vertebrates Brian A. Maurer,* James H. Brown, Tamar Dayan, Brian J. Enquist, S.K. Morgan Ernest, Elizabeth A. Hadly, John P. Haskell, David Jablonski, Kate E. Jones, Dawn M. Kaufman, S. Kathleen Lyons, Karl J. Niklas, Warren P. Porter, Kaustuv Roy, Felisa A. Smith, Bruce Tiffney and Michael R. Willig National Center for Ecological Analysis and Synthesis (NCEAS), Working Group on Body Size in Ecology and Paleoecology, 735 State Street, Suite 300, Santa Barbara, CA 93101-5504, USA ABSTRACT Since flight imposes physical constraints on the attributes of a flying organism, it is expected that the distribution of body sizes within clades of small-bodied flying vertebrates should share a similar pattern that reflects these constraints. We examined patterns in similarities of body mass distributions among five clades of small-bodied endothermic vertebrates (Passeriformes, Apodiformes + Trochiliformes, Chiroptera, Insectivora, Rodentia) to examine the extent to which these distributions are congruent among the clades that fly as opposed to those that do not fly. The body mass distributions of three clades of small-bodied flying vertebrates show significant divergence from the distributions of their sister clades. We examined two alternative hypotheses for similarities among the size frequency distributions of the five clades. The hypothesis of functional symmetry corresponds to patterns of similarity expected if body mass distributions of flying clades are constrained by similar or identical functional limitations. The hypothesis of phylogenetic symmetry corresponds to patterns of similarity expected if body mass distributions reflect phylogenetic relationships among clades.

    The Habitability of Planets Orbiting M-dwarf Stars Aomawa L. Shields1;2;4, Sarah Ballard3, John Asher Johnson4 1University of California, Irvine, Department of Physics and Astronomy, 4129 Frederick Reines Hall, Irvine, CA 92697, USA 2University of California, Los Angeles, Department of Physics and Astronomy, Box 951547, Los Angeles, CA 90095, USA 3Massachusetts Institute of Technology, 77 Massachusetts Ave, 37-241, Cambridge, MA 02139, USA 4Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, MA 02138, USA Abstract The prospects for the habitability of M-dwarf planets have long been debated, due to key differences between the unique stellar and planetary environments around these low-mass stars, as compared to hotter, more luminous Sun- like stars. Over the past decade, significant progress has been made by both space- and ground-based observatories to measure the likelihood of small planets to orbit in the habitable zones of M-dwarf stars. We now know that most M dwarfs are hosts to closely-packed planetary systems characterized by a paucity of Jupiter-mass planets and the presence of multiple rocky planets, with roughly a third of these rocky M-dwarf planets orbiting within the habitable zone, where they have the potential to support liquid water on their surfaces. Theoretical studies have also quantified the effect on climate and habitability of the interaction between the spectral energy distribution of M-dwarf stars and the atmospheres and surfaces of their planets. These and other recent results fill in knowledge gaps that existed at the time of the previous overview papers published nearly a decade ago by Tarter et al.

  • Generation of Earth's First-Order Biodiversity Pattern
    ASTROBIOLOGY Volume 9, Number 1, 2009 © Mary Ann Liebert, Inc. DOI: 10.1089/ast.2008.0253 Review Generation of Earth’s First-Order Biodiversity Pattern Andrew Z. Krug,1 David Jablonski,1 James W. Valentine,2 and Kaustuv Roy3 Abstract The first-order biodiversity pattern on Earth today and at least as far back as the Paleozoic is the latitudinal di- versity gradient (LDG), a decrease in richness of species and higher taxa from the equator to the poles. LDGs are produced by geographic trends in origination, extinction, and dispersal over evolutionary timescales, so that analyses of static patterns will be insufficient to reveal underlying processes. The fossil record of marine bivalve genera, a model system for the analysis of biodiversity dynamics over large temporal and spatial scales, shows that an origination and range-expansion gradient plays a major role in generating the LDG. Peak orig- ination rates and peak diversities fall within the tropics, with range expansion out of the tropics the predomi- nant spatial dynamic thereafter. The origination-diversity link occurs even in a “contrarian” group whose di- versity peaks at midlatitudes, an exception proving the rule that spatial variations in origination are key to Ն latitudinal diversity patterns. Extinction rates are lower in polar latitudes ( 60°) than in temperate zones and thus cannot create the observed gradient alone. They may, however, help to explain why origination and im- migration are evidently damped in higher latitudes. We suggest that species require more resources in higher latitudes, for the seasonality of primary productivity increases by more than an order of magnitude from equa- torial to polar regions.

  • Comparative Planetology and the Search for Life Beyond the Solar System
    Beichman et al.: The Search for Life Beyond the Solar System 915 Comparative Planetology and the Search for Life Beyond the Solar System Charles A. Beichman California Institute of Technology Malcolm Fridlund European Space Agency Wesley A. Traub and Karl R. Stapelfeldt Jet Propulsion Laboratory Andreas Quirrenbach University of Leiden Sara Seager Carnegie Institute of Washington The study of planets beyond the solar system and the search for other habitable planets and life is just beginning. Groundbased (radial velocity and transits) and spacebased surveys (tran- sits and astrometry) will identify planets spanning a wide range of size and orbital location, from Earth-sized objects within 1 AU to giant planets beyond 5 AU, orbiting stars as near as a few parsec and as far as a kiloparsec. After this initial reconnaissance, the next generation of space observatories will directly detect photons from planets in the habitable zones of nearby stars. The synergistic combination of measurements of mass from astrometry and radial velocity, of radius and composition from transits, and the wealth of information from the direct detection of visible and mid-IR photons will create a rich field of comparative planetology. Information on protoplanetary and debris disks will complete our understanding of the evolution of habitable environments from the earliest stages of planet formation to the transport into the inner solar system of the volatiles necessary for life. The suite of missions necessary to carry out the search for nearby, habitable planets and life requires a “Great Observatories” program for planet finding (SIM PlanetQuest, Terrestrial Planet Finder-Coronagraph, and Terrestrial Planet Finder-Interfer- ometer/Darwin), analogous to the highly successful “Great Observatories Program” for astro- physics.
