Red-edge position of habitable exoplanets around M-dwarfs
Scientific Reports, 2017 One of the possible signs of life on distant habitable exoplanets is the red-edge, which is a rise in the reflectivity of planets between visible and near-infrared (NIR) wavelengths.

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
