The mass of the white dwarf in GW Libra.

VAN SPAANDONK L., STEEGHS D., MARSH T.R. and PARSONS S.G.

Abstract (from CDS):

We report a mass and rotational broadening (vsin i) for the pulsating white dwarf (WD) component of the WZ Sge type Dwarf Nova GW Lib based on high-resolution Very Large Telescope spectroscopy that resolves the Mg II 4481 Å absorption feature. Its gravitational redshift combined with WD mass-radius models provides us with a direct measurement of the WD mass of M1= 0.84 ±0.02 M☉. The line is clearly resolved and if associated with rotational broadening gives vsin i = 87.0±3.4 km/s, equivalent to a spin period of 97±12 s.
