Mass-radius diagram for massive planets, brown dwarfs, and very low-mass stars transiting primaries with M_s> 0.5 M_⊙. The dashed lines are the isochrones of Baraffe et al. (2003) for ages of (from top to bottom) 0.5, 1, 5, and 10 Gyr. The dotted lines are the 5 Gyr Dartmouth isochrones (2012 version, Feiden & Chaboyer 2014) for the extreme allowed values for KOI-686, and for solar metallicity. The objects presented in this paper are plotted in red; other objects from the SOPHIE follow-up of Kepler candidates are labeled in blue.
