Description

We present results from nonadiabatic stability calculation to determine the position of the GW Vir band in the log g -Teff diagram. With this method, we calculate the position of seven GW Vir stars. The results are consistent with and complementary to the spectroscopic determination of atmospheric parameters and the chemical compositions of these stars except for the newly discover GW Vir star VV 47. This discrepancy is discussed.
