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. The discovery of the first brown dwarfs and planets were both announced at Cool Stars 9. Later, Chandra, XMM-Newton and Spitzer and more recently Kepler and the Solar Dynamics Observatory repeatedly made us re-write text books—no really, the missions and meetings directly led to new editions. This year, as TESS and Parker Solar Probe threaten to make us re-write the text books yet again, approximately 500 international experts in Low-Mass Stars, Solar Physics, and Exoplanets meet here, in Boston and Cambridge, to again exchange ideas in a cross-disciplinary and friendly environment. I would like to thank all of you for coming and bringing your ideas and your willingness to share. This meeting is a celebration of you and the work you do. Four institutions in the Boston area (Boston University, Harvard-Smithsonian Center for As- trophysics (Harvard College Observatory / Smithsonian Astrophysical Observatory), MIT, and University of Massachusetts Lowell) jointly organized Cool Stars 20 at Boston University in Boston/Cambridge, MA from July 29 to August 4, 2018. I would like to thank the Scientific Organizing Committee who developed the science pro- gram. For this meeting the Scientific topics are: • Galactic Cartography in the Gaia Era, • Solar/Stellar Environments, • Fundamental Properties of Cool Stars, • Solar/Stellar Magnetic Fields and Surface Structure, • Very Low Mass (VLM) Objects. iii The Science Organizing Committee chose the invited speakers, the hosts of the splinter ses- sions, and the contributed speakers for the plenary session. Overall, we accepted only 37 contributed talks out of 289 submissions to speak in the plenary session. This means a speak- ing opportunity in the plenary session was about as difficult to obtain as Hubble time. I would like to thank the international SOC for their efforts: Silvia Alencar, Fabienne Bastien, Sarbani Basu, Chas Beichman, Svetlana Berdyugina, Angela Bragaglia, Paul Charbonneau, Ofer Co- hen, Charlie Conroy, Andrea Dupree, Catherine Espaillat, Gregory Feiden, Lindsey Glesener, Suzanne Hawley, Dave Huenemoerder, Gaitee Hussain, Moira Jardine, Adam Kowalski, Phil Muirhead, Jürgen Schmitt, John Stauffer, Gerard van Belle. They held up under the weight of so many difficult decisions. They have some more work to do choosing the best posters and the host for Cool Stars 21. Within the SOC, I especially want to thank Phil and Catherine for making the facilities at BU available to us. This meeting has grown to 10 times its original size and finding a large venue with enough room for all of us near the Center of the Universe (Cambridge, MA) is difficult. I would also like to thank Nancy Brickhouse and Ed DeLuca for helping me write the original proposal to help bring this meeting home and for graciously stepping aside from the SOC to allow more people to contribute. The hardest work organizing this meeting falls to the local organizing committee. They are drawn from the host institutions and have been working almost since the day we left Uppsala. Their tasks range from writing the web-based software, to organizing the excursions, dealing with the AV equipment, badges, designing T-shirts, coffee mugs, and pilsner glasses, creat- ing the abstract book and lining up the banquet. This is a bit more complicated than it was in 1980. Thanks go to Rana Ezzeddine, Moritz Günther (chair), Jenine Humber, Nishu Karna, Aurora Kesseli, David Principe, Sam Quinn, Benjamin Roulston, Carl Schmidt, Julie Skinner, Anastasiia V Uvarova, Mark Veyette, Jen Winters. Kristin Ann Divona created our logos. I especially want to thank Jenine our single administrator responsible for making sure every bill got paid, every visa question got answered and every invitation was sent. I also want to single out Moritz for thanks. He runs a very tight ship on the LOC, writes the really excellent software that drives the knowledge base of the meeting and he reminds me when I am falling behind schedule. I would also be remiss not to thank our sponsors, Charles Alcock at the Harvard-Smithsonian Center for Astrophysics, Gloria Waters at Boston University, Chas Beichman at NExSci and Fabio Favata at ESA; all made significant contributions which helped us keep the overall cost of the meeting down and in many cases allowed us to waive registration entirely. Finally, I would like to thank Andrea Dupree. Without her efforts in 1980 and throughout the 80’s, 90’s and 00’s, none of us would be here now for CS 20. She has been a tremendous source of encouragement and inspiration to me. Here is to seeing you all at Cool Stars 40 in 2058 or so.

    Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born.

  • An Atlas of Far-Ultraviolet Spectra of the Zeta Aurigae Binary 31 Cygni with Line Identifications
    The Astrophysical Journal Supplement Series, 211:27 (14pp), 2014 April doi:10.1088/0067-0049/211/2/27 C 2014. The American Astronomical Society. All rights reserved. Printed in the U.S.A.

We present the coadded, calibrated spectra and atlases with line identifications. During total eclipse, emission from high ionization states (e.g., Fe iii and Cr iii) shows asymmetric profiles redshifted from the systemic velocity, while emission from lower ionization states (e.g., Fe ii and O i) appears more symmetric and is centered closer to the systemic velocity. Absorption from neutral and singly ionized elements is detected during chromospheric eclipse. Late in chromospheric eclipse, absorption from the K star wind is detected at a terminal velocity of ∼80 km s−1. These atlases will be useful for interpreting the far-UV spectra of other ζ Aur systems, as the observed FUSE spectra of 32 Cyg, KQ Pup, and VV Cep during chromospheric eclipse resemble that of 31 Cyg.

The Kepler mission has recently discovered a brown dwarf companion transiting one member of the M4V+M5V visual binary system LHS 6343 AB with an orbital period of 12.71 days. Aims. The particular interest of this transiting system lies in the synchronicity between the transits of the brown dwarf C component and the main modulation observed in the light curve, which is assumed to be caused by rotating starspots on the A component. We model the activity of this star by deriving maps of the active regions that allow us to study stellar rotation and the possible interaction with the brown dwarf companion. Methods. An average transit profile was derived, and the photometric perturbations due to spots occulted during transits are removed to derive more precise transit parameters. We applied a maximum entropy spot model to fit the out-of-transit optical modulation as observed by Kepler during an uninterrupted interval of 500 days.

  • A Review of Possible Planetary Atmospheres in the TRAPPIST-1 System
    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.

  • A Citation Study of Citizen Science Projects in Space Science and Astronomy
    Odenwald, S. 2018. A Citation Study of Citizen Science Projects in Space Science and Astronomy. Citizen Science: Theory and Practice, 3(2): 5, pp. 1–11. DOI: https://doi.org/10.5334/cstp.152 RESEARCH PAPER A Citation Study of Citizen Science Projects in Space Science and Astronomy Sten Odenwald This paper presents a citation study of 143 publications in refereed journals resulting from 23 citizen science (CS) projects in space science and astronomy. The projects generated a median of two papers during their average of six years of operation. The 143 papers produced 4,515 citations for a median of 10 citations/paper. These papers were compared to a uniform group of papers published in the year 2000 in refereed space science journals. The CS papers have an average annual peak citation rate that is about four times the average of the year-2000 sample. The CS citation history profiles peak within 3 years after paper publication but decline thereafter at a faster pace than the average paper published in 2000. This suggests that CS papers “burn brighter” but remain of interest for only half as long as other papers in space science and astronomy. Nevertheless, CS papers compare well with some of the most highly ranked “Top-1000” research papers of the modern era. The proportion of CS papers surpassing 200 citations is one-in-26, which is 40-fold higher than the proportion for the typical paper published in 2000. The study concludes that CS projects are not only as good as conventional non-CS research projects in generating publishable results, but can actually outperform the citation rates of the typical non-CS papers in space science and astronomy.
