Surface gravity vs. effective temperature as a proxy of the Hertzprung–Russell diagram. The black lines represent CESAM evolution model tracks for stellar masses ranging from 0.8 to 2.4 M⊙. The trigonometric surface gravities computed using the Gaia eDR3 parallaxes (orange circles) are in better agreement with the model tracks than the spectroscopic values (gray crosses) for the dwarf stars.
