Apparent radial velocity of rotating stars changes during planetary transits owing to the Rossiter-McLaughlin effect, here modeled for stars of three different temperatures (“K8 V”, “F7 V”, and “F3 V”) for the rotational velocities V sin i = 1 and 5 km s^-1 (solid blue and dashed red, respectively). The planet was assumed to cover 1.5% of the stellar disk area with the transit along the stellar equator. The signal was obtained as a Gaussian fit to the line profile in integrated starlight. The wavelength values reflect different amounts of convective blueshift and are also affected by rotational line broadening, while the amplitudes are a function of rotational velocity. Gravitational redshifts are neglected.
