Can a red dwarf host a habitable planet?

WIESSINGER The habitable zone is a region around a star where an Earth-mass planet with an Earth-like atmosphere would have a surface temperature of 0° to 100°C. Owen and Mohanty model planets in the habitable zone of red dwarfs, which are by far the most common type of star. These planets form with a hydrogen/helium envelope, and the greenhouse effect makes their surfaces too hot. Radiation from the star can strip away the envelope from a Venus-mass planet, causing it to fit the “habitable” criteria within a reasonable time. But the stronger gravity of an Earth-mass planet prevents it from ever losing enough of the envelope to cool down and become habitable. Mon. Not. R. Astron. Soc. 459 , 4088 (2016). [1]: pending:yes
