ESCAPE: a small explorer mission to study the stellar drivers of exoplanet evolution
Allison Youngblood, Kevin France, Brian Fleming +37
The long-term stability of exoplanetary atmospheres depends critically on the extreme-ultraviolet (EUV) photon and high-energy particle fluxes from the host star, which are poorly…
Mars as an Exoplanet: Lessons from a Planet at the Edge of Habitability
Stephen R. Kane, Paul K. Byrne, Skylar D'Angiolillo +5
Mars is the Solar System's canonical small, rocky planet that transitioned from early geologic activity and surface liquid water to a cold and arid planet with a thin, cold, CO…
Coupled Photochemical-Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets
Megan Gialluca, Victoria Meadows, Andrew Lincowski +4
Available JWST observations TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere. However, the high atmospheric esc…
Atmospheric Escape Rates from Mars - If it Orbited an Old M-Dwarf Star
David A. Brain, Ofer Cohen, Thomas E. Cravens +35
Atmospheric escape is an important process that influences the evolution of planetary atmospheres. A variety of physical mechanisms can contribute to escape from an atmosphere, inc…
Atmospheric collapse and re-inflation through impacts for terrestrial planets around M dwarfs
Prune C. August, Robin Wordsworth, Mikayla Huffman +2
Detection of an atmosphere around a terrestrial exoplanet will be a major milestone in the field, but our observational capacities are biased towards to tidally locked, close-in pl…
Simulations of Electron Beam Interactions in Brown Dwarf Atmospheres
Anna Zuckerman, J. Sebastian Pineda, David Brain +2
Over two decades ago, the first detection of electron cyclotron maser instability (ECMI) radio emission from a brown dwarf confirmed the presence of aurorally precipitating electro…
