Mass-density diagram for planets, brown dwarfs, and low-mass stars in eclipsing binaries with a precision in measured mass and density better than 20%. The star and diamond symbols mark the locations of EPIC 212036875 b and EPIC 219388192b also found by our programme (Nowak et al. 2017). The red dashed line represents a second-order polynomial fit to the data with M = 0.3–80 M_J and equilibrium temperatures <1000 K. The blue dashed line shows a linear fit to the stars with M > 80 M_J. The nominalseparation at 80 M_J between brown dwarfs and stars, and the empirical separation between low-mass and giant planets at 0.3 M_J are marked with the vertical dash-dotted lines. The solid black line shows the theoretical relationship for H/He dominated giant objectswith Z = 0.02, age = 5 Gyr, without irradiation (Baraffe et al. 2003, 2008), and the dotted black line the same model including irradiation from a solar-type star at 0.045 AU (Baraffe et al. 2008).
