Left panel: masses and radii of the known transiting extrasolar planets. The grey points denote values taken from TEPCat. Their error bars have been suppressed for clarity. HATS-13b and HATS-14b are shown in red points with error bars. Dotted lines show where density is 2.5, 1.0, 0.5, 0.25 and 0.1 ρ_J. Right panel: the mass-density diagram of the currently known transiting exoplanets (taken from TEPCat). Again HATS-13b and HATS-14b are shown in red points with error bars. Four planetary models with various core masses (10, 25, 50, and 100 Earth mass) and another without a core (Fortney et al. 2007) are plotted for comparison.
