Abstract:
Evolutionary stellar models of FG Vir have been developed theoretically and are compared with earlier observational results. Using the models, we performed calculations to obtain radial and non-radial adiabatic oscillation frequencies. The results show that, if the observational splitting was considered and the observational mode identifications were followed, 1.85M⊙ star models with the rotational velocities in the range from 32 to 66 kms−1 seem to be representative models of FG Vir.
