Mean stellar density versus T_eff diagram. The colored areas correspond to the values derived from (i) in green, the spectroscopic analysis, the log g being converted into mean density; (ii) in blue, the atmospheric parameters derived from the spectroscopic analysis combined with the mean stellar density from the transit fitting; (iii) in red, the best model obtained by modeling the SED, the light curve, and the radial velocity measurements. The contours correspond to the 1σ, 2σ, and 3σ regions. The curves are STAREVOL stellar evolutionary tracks plotted for a few masses as labeled, and for each mass with two different metallicities: 0.2 (solid line) and 0.3 (dashed line).
