Atmospheric escape from the TRAPPIST-1 planets and implications for habitability [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance The search for exoplanets has rapidly emerged as one of the most important endeavors in astronomy. This field received a major impetus with the recent discovery of seven temperate Earth-sized exoplanets orbiting the nearby ultracool dwarf ...

Records of mantle geodynamics and atmospheric escape in Archean quartz. [PDF]
Sci AdvEarly planetary degassing and atmospheric escape are two major, yet unconstrained, processes that shaped early Earth. Modeling predicts that the atmospheric 20Ne/22Ne ratio is sensitive to solar-Ne mantle degassing over geological time.

Atmospheric Escape Processes and Planetary Atmospheric Evolution [PDF]
Journal of Geophysical Research: Space Physics, 2020 The habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars drive thermal, chemical, and physical alteration of planetary atmospheres ...

Atmospheric Escape From Three Terrestrial Planets in the L 98-59 System [PDF]
The Astrophysical Journal, 2023 A critically important process affecting the climate evolution and potential habitability of an exoplanet is atmospheric escape, in which high-energy radiation from a star drives the escape of hydrogen atoms and other light elements from a planet’s ...
