Habitable Zone and Atmosphere Retention Distance (HaZARD) Stellar-evolution-dependent Loss Models of Secondary Atmospheres - Astrobiology

A major open question in exoplanet research is whether secondary atmospheres are rare around Earth-sized rocky exoplanets. In this work we determine the distance at which an Earth-sized planet orbiting a variety of stellar hosts could retain a CO2– or N2-dominated atmosphere and compare this atmospheric retention distance (ARD) with that of the liquid-water HZ.
