Companion mass over stellar effective temperature T_eff diagram for massive planets (M_P > 3 M_Jup, from the updated exoplanet catalog of Otegi et al. 2020) and transiting brown dwarfs (Table 3) shown in blue. The four new companions are shown in yellow. The red circles display confirmed companions detected by TESS. The size scales inversely with the period of the companion. The red, vertical line corresponds to the Kraft break (6200 K) while the horizontal lines correspond to the approximate boundaries of the brown dwarf regime (13 M_Jup) and the transition to high-mass brown dwarfs (42.5 M_Jup).
