Photosynthesis on Habitable Planets Around low-mass Stars
We show that planets around M-dwarfs with M⋆≲0.2M⊙ may not receive enough photons in the photosynthetically active range of 400-750 nm to sustain Earth-like biospheres.
As a result of the lower biological productivity, it is likely that biotic molecular oxygen will not build up to detectable levels in the atmospheres of habitable planets orbiting low-mass stars.
