NLTT5306: The shortest Period Detached White Dwarf + Brown Dwarf Binary
P. R. Steele, R. P. Saglia, M. R. Burleigh +6
We have spectroscopically confirmed a brown dwarf mass companion to the hydrogen atmosphere white dwarf NLTT5306. The white dwarf's atmospheric parameters were measured using Sloan…
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…
PHL 5038: A spatially resolved white dwarf + brown dwarf binary
P. R. Steele, M. R. Burleigh, J. Farihi +4
A near-infrared excess is detected at the white dwarf PHL5038 in UKIDSS photometry, consistent with the presence of a cool, substellar companion. We have obtained H- and K-grism sp…
