Deuterium Escape on Photoevaporating Sub-Neptunes
Pin-Gao Gu, Howard Chen
We investigate the evolution of the deuterium-to-hydrogen (D/H) mass ratio driven by EUV photoevaporation of hydrogen-rich atmospheres of close-in sub-Neptunes around solar-type st…
Sporadic Spin-Orbit Variations in Compact Multi-planet Systems and their Influence on Exoplanet Climate
Howard Chen, Gongjie Li, Adiv Paradise +1
Climate modeling has shown that tidally influenced terrestrial exoplanets, particularly those orbiting M-dwarfs, have unique atmospheric dynamics and surface conditions that may en…
Impact Induced Atmosphere-Mantle Exchange Sets the Volatile Elemental Ratios on Primitive Earths
Howard Chen, Seth A. Jacobson
Conventional planet formation theory suggests that chondritic materials have delivered crucial atmospheric and hydrospheric elements such as carbon (C), nitrogen (N), and hydrogen…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
TRAPPIST Habitable Atmosphere Intercomparison (THAI) workshop report
Thomas J. Fauchez, Martin Turbet, Denis E. Sergeev +31
The era of atmospheric characterization of terrestrial exoplanets is just around the corner. Modeling prior to observations is crucial in order to predict the observational challen…
Persistence of Flare-Driven Atmospheric Chemistry on Rocky Habitable Zone Worlds
Howard Chen, Zhuchang Zhan, Allison Youngblood +3
Low-mass stars show evidence of vigorous magnetic activity in the form of large flares and coronal mass ejections. Such space weather events may have important ramifications for th…
