Abstract:
The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will
obtain space-based uninterrupted light curves for a large sample of
bright white dwarfs distributed across the entire sky, providing a
very rich resource for asteroseismological studies and the search for
transits from planetary debris. We have compiled an all-sky catalogue
of ultraviolet, optical and infrared photometry as well as proper
motions, which we propose as an essential tool for the preliminary
identification and characterization of potential targets. We present
data for 1864 known white dwarfs and 305 high-probability white dwarf
candidates brighter than 17mag. We describe the spectroscopic
follow-up of 135 stars, of which 82 are white dwarfs and 25 are hot
subdwarfs. The new confirmed stars include six pulsating white dwarf
candidates (ZZ Cetis), and nine white dwarf binaries with a cool main-
sequence companion. We identify one star with a spectroscopic distance
of only 25pc from the Sun. Around the time TESS is launched, we
foresee that all white dwarfs in this sample will have trigonometric
parallaxes measured by the ESA Gaia mission next year.
Description:
This photometric and reduced proper motion catalogue was created to
identify suitable targets for the space-borne mission TESS, which will
acquire all- sky time-series photometry for at least two years
searching for exoplanet transits and enabling asteroseismology for
numerous classes of stars. We cross-matched APASS, GALEX, 2MASS, and
WISE, with PPMXL.The attached data include current-epoch positions and
photometry of known white dwarfs, candidate white dwarfs, and new
spectroscopically confirmed white dwarfs. For the new stars, we
estimated the atmospheric parameters (temperature and surface
gravity), masses, and ages. Nine white dwarfs have low mass
secondaries, for which we estimate temperatures and ages.
