Post-common envelope binaries from SDSS - VII: A catalogue of white dwarf-main sequence binaries
A. Rebassa-Mansergas, B. T. Gaensicke, M. R. Schreiber +2
We present a catalogue of 1602 white dwarf-main sequence binaries (WDMS) from the spectroscopic Sloan Digital Sky Survey Data Release 6 (SDSS DR6). Among these we identify 440 as n…
High-resolution UVES/VLT spectra of white dwarfs observed for the ESO SN Ia Progenitor Survey. III. DA white dwarfs
D. Koester, B. Voss, R. Napiwotzki +5
The ESO Supernova Ia Progenitor Survey (SPY) took high-resolution spectra of more than 1000 white dwarfs and pre-white dwarfs. About two thirds of the stars observed are hydrogen-d…
Detecting short period variable stars with Gaia
M. Varadi, L. Eyer, S. Jordan +2
We analyzed the frequency domain of time series of simulated ZZ Ceti light-curves to investigate the detectability and period recovery performance of short period variables (period…
Accretion and diffusion in white dwarfs. New diffusion timescales and applications to GD362 and G29-38
D. Koester
A number of cool white dwarfs with metal traces, of spectral types DAZ, DBZ, and DZ have been found to exhibit infrared excess radiation due to circumstellar dust. The origin of th…
