A Trio of Metal-Rich Dust and Gas Disks Found Orbiting Candidate White Dwarfs with K-Band Excess
J. Farihi, B. T. Gänsicke, P. R. Steele +4
This paper reports follow-up photometric and spectroscopic observations, including warm Spitzer IRAC photometry of seven white dwarfs from the SDSS with apparent excess flux in UKI…
A precision study of two eclipsing white dwarf plus M dwarf binaries
S. G. Parsons, T. R. Marsh, B. T. Gänsicke +16
We use a combination of X-shooter spectroscopy, ULTRACAM high-speed photometry and SOFI near-infrared photometry to measure the masses and radii of both components of the eclipsing…
White dwarfs in the UKIDSS Large Area Survey: The Substellar Companion Fraction
P. R. Steele, M. R. Burleigh, P. D. Dobbie +3
We present a near-infrared photometric search for unresolved substellar companions and debris disks around white dwarfs in the UKIRT Infrared Deep Sky Survey Large Area Survey. We…
On the Origin of Metals in Some Hot White Dwarf Photospheres
M. R. Burleigh, M. A. Barstow, J. Farihi +6
We have searched for evidence for dust and gas disks at a sample of hot DA white dwarfs 20 000K < Teff < 50 000K, without success. Although their atmospheres are polluted with heav…
Brown Dwarf Companions to White Dwarfs
M. R. Burleigh, P. R. Steele, P. D. Dobbie +8
Brown dwarf companions to white dwarfs are rare, but recent infra-red surveys are slowly reveal- ing examples. We present new observations of the post-common envelope binary WD0137…
