Radius-mass diagram including transiting companions more massive than 10 M_Jup. The dashed curves are the Baraffe et al. (2003) isochrones for 0.5, 1, 5, and 10 Gyr (from top to bottom). Both circular (filled red circle) and eccentric (empty red circle) solutions are shown for Kepler-39b. Blue labels indicate the brown dwarfs and low-mass stars that were characterized thanks to SOPHIE spectroscopic measurements (see also Moutou et al. 2013; Díaz et al. 2014).
