The Takeaway
Astronomers are currently debating if planets orbiting small, active stars can hold onto their air or if they get stripped bare. This paper 'breaks' the fourth wall of science by using the Star Wars universe as a comprehensive data set to argue that these planets are likely habitable and air-rich.
From the abstract
Whether there is a cosmic shoreline that divides terrestrial planets which have atmospheres from those that don't is one of the biggest open questions in exoplanet science. Most atmosphere searches have focused on terrestrial planets around M dwarf stars, since their smaller radii compared to sun-like stars boost planet atmosphere signals. However, the higher activity levels of M dwarfs might also entirely preclude atmosphere retention for their planets. In this work we present a new hope for de
