Influence of the obliquity β. Parameters are set to their default values and ω = ω_eq = 2.38n. Panels a) and b): lightcurves for different obliquities and two orientations of the spin axis, without tidal heating. Panels c) and d): Same as b) but with tidal heating included, uniformly in c) and with half of the tidal dissipation released through one hot spot (Gaussian, half width: 45°) centered on the equator in d).
