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

【摘要】 <正>Taking into consideration the effects of rotation and interior magnetic field dur- ing the lifetime of the star,we reconstruct the model ofαCen B to satisfy the latest non- asteroseismic and asteroseismic observational constraints.We find that the effects can induce a change of about 0.3μHz in the large frequency spacings and can speed up the star’s evolu- tion.The model ofαCen B has thereby been improved.更多还原
