Abstract:	GWVir variables are the pulsating members in the spectroscopic class of PG1159 stars. In order to understand the characteristic differences between pulsating and non-pulsating PG1159 stars, we analyse FUSE spectra of eleven objects, of which six are pulsating, by means of state-of-the-art NLTE model atmospheres. The numerous metal lines in the FUV spectra of these stars allow a precise determination of the photospheric parameters. We present here preliminary results of our analysis.
