Impact of hot and cold accretion, and of the core mass on the temporal evolution of the planetary M−total L diagram. The blue empty circles are the cold-nominal population. The red stars are the hot population with hot gas accretion and otherwise identical assumptions. The black and gray filled circles represent planets in the cold-classical population. Planets with a core mass of less than 17 M_⊕ in this population are shown with black dots and those with a core mass above than 17 M_⊕ in gray. This mimics the classical cold start models of Marley et al. (2007). In the panel at 20 Myr the lines shows possible M−L relations for β Pictoris b and 51 Eridani b.
