Measuring the D/H Ratios of Exoplanets and Brown Dwarfs
Caroline V. Morley, Andrew J. Skemer, Brittany E. Miles +5
The relative abundance of deuterium and hydrogen is a potent tracer of planet formation and evolution. Jupiter and Saturn have protosolar atmospheric D/H ratios, a relic of substan…
Do close-in giant planets orbiting evolved stars prefer eccentric orbits?
Samuel K. Grunblatt, Daniel Huber, Eric Gaidos +7
The NASA Kepler and K2 Missions have recently revealed a population of transiting giant planets orbiting moderately evolved, low-luminosity red giant branch stars. Here, we present…
Highly Volcanic Exoplanets, Lava Worlds, and Magma Ocean Worlds: An Emerging Class of Dynamic Exoplanets of Significant Scientific Priority
Wade G. Henning, Joseph P. Renaud, Prabal Saxena +39
Highly volcanic exoplanets, which can be variously characterized as 'lava worlds', 'magma ocean worlds', or 'super-Ios' are high priority targets for investigation. The term 'lava…
Exoplanet Science Priorities from the Perspective of Internal and Surface Processes for Silicate and Ice Dominated Worlds
Wade G. Henning, Joseph P. Renaud, Avi M. Mandell +35
The geophysics of extrasolar planets is a scientific topic often regarded as standing largely beyond the reach of near-term observations. This reality in no way diminishes the cent…
Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars III: A High Mass & Low Envelope Fraction for the Warm Neptune K2-55b
Courtney D. Dressing, Evan Sinukoff, Benjamin J. Fulton +23
K2-55b is a Neptune-sized planet orbiting a K7 dwarf with a radius of , a mass of , and an effective temperature of $4300^{+1…
An accurate mass determination for Kepler-1655b, a moderately-irradiated world with a significant volatile envelope
R. D. Haywood, A. Vanderburg, A. Mortier +32
We present the confirmation of a small, moderately-irradiated (F = 155 +/- 7 Fearth) Neptune with a substantial gas envelope in a P=11.8728787+/-0.0000085-day orbit about a quiet,…
Exoplanet Diversity in the Era of Space-based Direct Imaging Missions
Ravi Kopparapu, Eric Hebrard, Rus Belikov +55
This whitepaper discusses the diversity of exoplanets that could be detected by future observations, so that comparative exoplanetology can be performed in the upcoming era of larg…
The Importance of Multiple Observation Methods to Characterize Potentially Habitable Exoplanets: Ground- and Space-Based Synergies
Giada Arney, Natasha Batalha, Nicolas Cowan +8
The discovery of a truly habitable exoplanet would be one of the most important events in the history of science. However, the nature and distribution of habitable environments on…
Eyes on K2-3: A system of three likely sub-Neptunes characterized with HARPS-N and HARPS
M. Damasso, A. S. Bonomo, N. Astudillo-Defru +67
M-dwarf stars are promising targets for identifying and characterizing potentially habitable planets. K2-3 is a nearby (45 pc), early-type M dwarf hosting three small transiting pl…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
An ultra-short period rocky super-Earth with a secondary eclipse and a Neptune-like companion around K2-141
Luca Malavolta, Andrew W. Mayo, Tom Louden +44
Ultra-short period (USP) planets are a class of low mass planets with periods shorter than one day. Their origin is still unknown, with photo-evaporation of mini-Neptunes and in-si…
