Abstract: Close-in planets undergo strong tidal effects with their host stars that modify their spins and orbits. Adopting a Maxwell rheology, it has been shown that for the 5/2 and 7/2 spin-orbit resonances, the obliquity of these planets can stabilise at a high value. Here, we show that these high obliquity metastable states can also be observed for the same spin-orbit resonances considering the Andrade rheology.
