| Abstract: |
Two different studies are presented: 1) a preliminary and exploratory study of the influence of including rotation in the evolutionary models from an asteroseismological point of view, and 2) variations of the colour index where the distortion of the stellar surface and the gravity darkening law are taken into account. The equilibrium models are provided by the Granada code, including rotation following the equipotential method described by Kippenhahn & Thomas (1970). The asteroseismological study can only be an estimation since the non-adiabatic pulsational code (Moya et al. 2004) does not include any rotational term (e.g. Coriolis, centrifugal force, etc.). Nevertheless some information can be obtained. For slow rotation compared with the break{up velocity, the spherically symmetric approximation can be accurate enough for preliminary asteroseismological results. On the other hand, we present colour index variations of rotating models respect to the non{rotating ones. By integration of the atmospheric fluxes, the CMD can be constructed allowing a direct comparison with observations. |
