All red dwarfs are flare stars, with solar winds 10 times stronger, they heat less so planets must be closer which makes it even worse.

- Symmetry 5y agoYeah. One danger for life is the star cooking it. But the other is that the solar wind will tend to strip away a planets hydrogen if life doesn't develop photosynthesis to give the planet an ozone layer fast enough. It took life on Earth most of a billion years[1] fooling around with chemosynthesis before photosynthesis took off. It's a hard step and life around a red dwarf would be on a much more stringent timeframe than life on our planet was.
