Planets of Red Dwarf Stars May Face Oxygen Loss in Habitable Zones (video) NASA/Goddard Space Flight Center Share Print E-Mail Loading video... Caption In this artist's concept, X-ray and extreme ultraviolet light from a young red dwarf star cause ions to escape from an exoplanet's atmosphere. Scientists have developed a model that estimates the oxygen ion escape rate on planets around red dwarfs, which plays an important role in determining an exoplanet's habitability.
