The mass-luminosity relation of giant planets at the moment when the protoplanetary disk disappears. As in Fig. 12, the blue empty circles are the cold-nominal population while the red stars show the hot population. The black and gray dots show the cold-classical population where black symbols correspond to planets with M_core ≤ 17 M_⊕. Note the significant spread in post-formation luminosities of more than two orders of magnitude at a given mass. The four black lines gives scalings for the hottest, cold-nominal, cold-classical (warm), and coldest M−L_pf relation discussed in the text.
