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…
The Electromagnetic Counterpart of the Binary Neutron Star Merger LIGO/VIRGO GW170817. III. Optical and UV Spectra of a Blue Kilonova From Fast Polar Ejecta
M. Nicholl, E. Berger, D. Kasen +31
We present optical and ultraviolet spectra of the first electromagnetic counterpart to a gravitational wave (GW) source, the binary neutron star merger GW170817. Spectra were obtai…
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…
Two white dwarfs in ultrashort binaries with detached, eclipsing, likely substellar companions detected by K2
S. G. Parsons, J. J. Hermes, T. R. Marsh +19
Using data from the extended Kepler mission in K2 Campaign 10 we identify two eclipsing binaries containing white dwarfs with cool companions that have extremely short orbital peri…
