M8 stars are almost certainly not going to have photosynthetic life. Almost no light in the visible spectrum. Sad, since it seems like rocky "earth-like" planets may be much more common around red dwarfs than yellow stars like ours.

High gravity, possible dense atmosphere, and thick oceans could still allow one or more of Trappist's planets to have black smoker or radiation eating deep rock inhabiting type life.
