An explanation for the gap in the Gaia HRD for M dwarfs [SSA]

http://arxiv.org/abs/1806.11454


We show that the recently discovered narrow gap in the Gaia Hertzsprung – Russell Diagram near MG =10 can be explained by standard stellar evolution models and results from a dip in the luminosity function associated with mixing of 3He during merger of envelope and core convection zones that occurs for a narrow range of masses.
