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(circle dot) star models with the rotational velocities in the range from 32 to 66 kms(-1) seem to be representative models of FG Vir.
