Main sequence showing the Geneva stellar evolution tracks for solar metallicity as presented in Mowlavi et al. (2011) and plotted using R _⋆  (in R_⊙) as a function of T_eff. Tracks are labelled in units of M_⊙. Dashed line show the 2 Gyr isochrone. Overplotted are the systems for which we have Rossiter-McLaughlin measurements. Aligned systems are red circles, misaligned systems are blue triangles. Higher metallicities will move the tracks to the right. Data obtained from Exoplanet.eu.
