English: M-dwarfs go from partly convective to fully convective and this is seen in the Hertzsprung–Russell diagram (Jao et al. 2018). To create this diagram I used ESA's Gaia Archive and the following selection method: G-mag<20, plx>15, astrometric_sigma5d_max<0.5 The stars plotted here are therefore closer than 217 light-years (67 parsec).
