Asteroseismic Analysis of α Cen B: Preliminary Tests of Effects of Rotation and Interior Magnetic Field in the Solar-like Star

Abstract

Taking into consideration the effects of rotation and interior magnetic field during the lifetime of the star, we reconstruct the model of a Cen B to satisfy the latest non-asteroseismic and asteroseismic observational constraints. We find that the effects can induce a change of about 0.3 mu Hz in the large frequency spacings and can speed up the star's evolution. The model of a Cen B has thereby been improved.
