Towards a dynamical mass of a PG 1159 star: radial velocities and spectral analysis of SDSS J212531-010745.

BEECK B., SCHUH S., NAGEL T. and TRAULSEN I.

Abstract (from CDS):

The evolutionary scenarios which are commonly accepted for PG 1159 stars are mainly based on numerical simulations, which have to be tested and calibrated with real objects with known stellar parameters. One of the most crucial but also quite uncertain parameters is the stellar mass. PG 1159 stars have masses between 0.5 and 0.8∼M_☉, as derived from asteroseismic and spectroscopic determinations. Such mass determinations are, however, themselves model-dependent. Moreover, asteroseismically and spectroscopically determined masses deviate systematically for PG 1159 stars by up to 10%.
