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 Mass Flux as a Function of Ionospheric Emission on Unmagnetized Earth
P. C. Hinton, D. A. Brain, N. R. Schnepf +3
We explore ion escape from, and solar ion deposition to, \hll{an unmagnetized Earth-like planet}. We use RHybrid, an ion-kinetic electron-fluid code to simulate the global plasma i…
