We present and explore a new method involving a 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 two GW Vir stars, PG 1159-035, log g = 6.80, Teff = 144, 500 K and PG 1707+427, log g = 7.38, Teff = 81, 500 K. The results are consistent with and complementary to the spectroscopic determination of atmospheric parameters and the chemical compositions of these stars.
