Measurements of the surface gravities of the ten very-low-mass stars, plotted against the stellar mass. The surface gravity is derived independently of the primary star mass, measurements of the surface gravity and mass are therefore uncorrelated. The Exeter/Lyon (Baraffe et al. 2015, 1998, 2003) 1 Gy (red) and 5 Gy (blue) isochrones are shown, for solar metallicity, [Fe/H] = 0.0 dex (solid line), and sub-solar metallicity, [Fe/H] = −0.5 dex (dashed line).
