Evolution of an Early Titan Atmosphere: Comment
Robert E Johnson, Orenthal J. Tucker, Alexey N. Volkov
Escape of an early atmosphere from Titan, during which time NH3 could be converted by photolysis into the present N2 dominated atmosphere, is an important problem in planetary scie…
Molecular-Kinetic Simulations of Escape from the Ex-planet and Exoplanets: Criterion for Transonic Flow
Robert E. Johnson, Alexey N. Volkov, Justin T. Erwin
The equations of gas dynamics are extensively used to describe atmospheric loss from solar system bodies and exoplanets even though the boundary conditions at infinity are not uniq…
Thermally driven escape from Pluto's atmosphere: A combined fluid/kinetic model
O. J. Tucker, J. T. Erwin, J. I. Deighan +2
A combined fluid/kinetic model is developed to calculate thermally driven escape of N2 from Pluto's atmosphere for two solar heating conditions: no heating above 1450 km and solar…
Thermally-driven atmospheric escape: Transition from hydrodynamic to Jeans escape
Alexey N. Volkov, Robert E. Johnson, Orenthal J. Tucker +1
Thermally-driven atmospheric escape evolves from an organized outflow (hydrodynamic escape) to escape on a molecule by molecules basis (Jeans escape) with increasing Jeans paramete…
