摘要
We derive the theoretical red edge of the pulsating GW Vir stars by using full evolutionary calculations that involve mass loss and diffusion. We put the emphasis on the fact that the specific mass loss law used in the evolutionary computations determines the red edge's position. By combining this specific property with the observed location of the red edge in the effective temperature-surface gravity domain, we obtain interesting constraints on possible mass loss laws for PG 1159 stars.
