Reply to comment by flipmcf in A Nearby Star Has Completely Blasted Away the Atmosphere From its Planet by Tao_Dragon

One more point against habitable planets around M class stars is that they are likely tidally locked due to the close orbits around the star - even in the Goldilocks zone. Maybe the biggest M class star could have a non-tidally locked planet in its GZ, but that would have to be a young star I guess.

Planets orbiting m dwarfs are not necessarily tidally locked. Spin-orbit resonances likely play a big role in compact multi planet systems.
