Factors affecting exoplanet habitability

VS Meadows, RK Barnes - Handbook of exoplanets, 2018 - ui.adsabs.harvard.edu
Habitability is a measure of an environment's potential to support life, and for exoplanets this
is tied to the presence of surface liquid water. Whether or not an exoplanet is able to …
