In this work we study the effects of rotating stars on the behavior of bosons close to their surfaces. For this task, metrics determined by the rotation of these stars will be taken into account. We will consider the Klein–Gordon equation in the Hartle–Thorne metric and in the one proposed by Berti et al. by considering some kinds of stars. Pions and Higgs bosons will be investigated as examples. By solving the equations, the main effect that may be observed is a rotational phase, 
, that depends on the angular momentum of the star, J, in the wave function of the boson. Corrections of higher orders in J are also investigated.
