Physical constraints on the likelihood of life on exoplanets [PDF]
, 2017 One of the most fundamental questions in exoplanetology is to determine whether a given planet is habitable. We estimate the relative likelihood of a planet's propensity towards habitability by considering key physical characteristics such as the role of
