Stellar temperature impact, in RVs, in the limb-darkening laws. Top row: RM curve (computed with ARoME), with increasing spin-orbit misalignment, for three temperatures in the temperature range of the FGK stars. Middle and bottom row: residuals’ variation (in tenths of cm s⁻¹) between a linear and a quadratic law. The RV scale is constant to emphasize the variation of the residuals’ amplitude with stellar temperature.
