Stellar parameters from Table 1 (shaded area) compared to Padova stellar evolution models (solid line) and Y² models (dashed line). We note that the models differ slightly in their chemical composition. The bold regions on the tracks indicate the ratio of the stellar radius to the semi-major axis of the planetary orbit derived from its orbital period, the mass of the stellar model, and Kepler’s third law. The “+” symbols indicate 1 Gyr time steps.
