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…

Habitability and Spectroscopic Observability of Warm M-dwarf Exoplanets Evaluated with a 3D Chemistry-Climate Model
Howard Chen, Eric T. Wolf, Zhuchang Zhan +1
Planets residing in circumstellar habitable zones (CHZs) offer our best opportunities to test hypotheses of life's potential pervasiveness and complexity. Constraining the precise…

Biosignature Anisotropy Modeled on Temperate Tidally Locked M-dwarf Planets
Howard Chen, Eric T. Wolf, Ravi Kopparapu +2
A planet's atmospheric constituents (e.g., O, O, HO, CO, CH, NO) can provide clues to its surface habitability, and may offer biosignature targets for r…
