Eclipsing Post Common Envelope Binaries from the Catalina Surveys
S. G. Parsons, B. T. Gänsicke, T. R. Marsh +6
We analyse the Catalina Real-time Transient Survey light curves of 835 spectroscopically confirmed white dwarf plus main-sequence binaries from the Sloan Digital Sky Survey (SDSS)…
An accurate mass and radius measurement for an ultracool white dwarf
S. G. Parsons, B. T. Gänsicke, T. R. Marsh +6
Studies of cool white dwarfs in the solar neighbourhood have placed a limit on the age of the Galactic disk of 8-9 billion years. However, determining their cooling ages requires t…
The chemical diversity of exo-terrestrial planetary debris around white dwarfs
B. T. Gaensicke, D. Koester, J. Farihi +3
We present HST ultraviolet spectroscopy of the white dwarfs PG0843+516, PG1015+161, SDSS1228+1040, and GALEX1931+0117, which accrete circumstellar planetary debris formed from the…
Gaseous Material Orbiting the Polluted, Dusty White Dwarf HE1349-2305
Carl Melis, P. Dufour, J. Farihi +6
We present new spectroscopic observations of the polluted, dusty, helium-dominated atmosphere white dwarf star HE1349-2305. Optical spectroscopy reveals weak CaII infrared triplet…
A Spitzer Space Telescope Study of the Debris Disks around four SDSS White Dwarfs
Carolyn Brinkworth, Boris Gaensicke, Jon Girven +4
We present Spitzer Space Telescope data of four isolated white dwarfs that were previously known to harbor circumstellar gaseous disks. IRAC photometry shows a significant infrared…
