Fraction of stars able to form a > 0.3ME HZ planet as a function of stellar mass. We assume an fZ distribution that is
gaussian with a standard deviation of 0.5 dex, and a fixed value of h = 1. The inset shows the effect of varying the limiting mass for
habitability from 0.1 to 0.5 ME, for α = h = 1.
A decreased probability of habitable planet formation around low-mass stars
