Abstract
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.
