Scatter plot of the companion masses versus stellar irradiations for our sample of 13 DI low-mass substellar companions. The dotted vertical bars indicate the rough positions of the molecular snowlines, assuming that they only depend on the stellar irradiation. The horizontal grey line shows the Deuterium Burning limit of 13 M_J that separates the brown dwarfs from the exoplanets (Spiegel et al. 2011). From left to right are AF Lep b, HR 8799 e, HR 2562 B, HR 8799 c, HIP 79098 (AB) B, HIP 78530 B, AB Pic b, 1RXSJ1609 b, ROXs 42 B b, ROXs 12 b, VHS 1256 b, 2MJ0219 b, and CT Cha b. The colours match the results presented below.
