A 15.7-Minute AM CVn Binary Discovered in K2
M. J. Green, J. J. Hermes, T. R. Marsh +14
We present the discovery of SDSS J135154.46-064309.0, a short-period variable observed using 30-minute cadence photometry in K2 Campaign 6. Follow-up spectroscopy and high-speed ph…
Rapid Evolution of the Gaseous Exoplanetary Debris Around the White Dwarf Star HE 1349--2305
E. Dennihy, J. C. Clemens, B. H. Dunlap +3
Observations of heavy metal pollution in white dwarf stars indicate that metal-rich planetesimals are frequently scattered into star-grazing orbits, tidally disrupted, and accreted…
Destroying Aliases from the Ground and Space: Super-Nyquist ZZ Cetis in K2 Long Cadence Data
Keaton J. Bell, J. J. Hermes, Z. Vanderbosch +5
With typical periods of order 10 minutes, the pulsation signatures of ZZ Ceti variables (pulsating hydrogen-atmosphere white dwarf stars) are severely undersampled by long-cadence…
WIRED for EC: New White Dwarfs with Infrared Excesses and New Classification Schemes from the Edinburgh-Cape Blue Object Survey
E. Dennihy, J. C. Clemens, John H. Debes +4
We present a simple method for identifying candidate white dwarf systems with dusty exoplanetary debris based on a single temperature blackbody model fit to the infrared excess. We…
White Dwarf Rotation as a Function of Mass and a Dichotomy of Mode Linewidths: Kepler Observations of 27 Pulsating DA White Dwarfs Through K2 Campaign 8
J. J. Hermes, B. T. Gaensicke, Steven D. Kawaler +15
We present photometry and spectroscopy for 27 pulsating hydrogen-atmosphere white dwarfs (DAVs, a.k.a. ZZ Ceti stars) observed by the Kepler space telescope up to K2 Campaign 8, an…
A catalogue of white dwarf candidates in VST ATLAS
Nicola Pietro Gentile Fusillo, Roberto Raddi, Boris T. Gänsicke +6
The Sloan Digital Sky Survey (SDSS) has created a knowledge gap between the Northern and the Southern hemispheres which is very marked for white dwarfs: only % of the kn…
