Mode Instability and a Massive, Isolated Outburst in the Pulsating White Dwarf GD 1212
J. J. Hermes, Keaton J. Bell, Andrew H. Dublin +8
We analyze a large brightening event that lasted for roughly half a day in the pulsating hydrogen-atmosphere white dwarf GD 1212 during K2 Campaign 12 of the extended Kepler missio…
NGTS and HST insights into the long period modulation in GW Librae
P. Chote, B. T. Gaensicke, J. McCormac +17
Light curves of the accreting white dwarf pulsator GW Librae spanning a 7.5 month period in 2017 were obtained as part of the Next Generation Transit Survey. This data set comprise…
The pulsating white dwarf G117-B15A: still the most stable optical clock known
S. O. Kepler, D. E. Winget, Zachary P. Vanderbosch +14
The pulsating hydrogen atmosphere white dwarf star G 117-B15A has been observed since 1974. Its main pulsation period at 215.19738823(63) s, observed in optical light curves, varie…
V1460 Her: A fast spinning white dwarf accreting from an evolved donor star
R. P. Ashley, T. R. Marsh, E. Breedt +6
We present time-resolved optical and ultraviolet spectroscopy and photometry of V1460~Her, an eclipsing cataclysmic variable with a 4.99\,h orbital period and an overluminous K5-ty…
An ultra-massive white dwarf with a mixed hydrogen-carbon atmosphere as a likely merger remnant
Mark A. Hollands, Pier-Emmanuel Tremblay, Boris T. Gänsicke +11
White dwarfs are dense, cooling stellar embers consisting mostly of carbon and oxygen, or oxygen and neon (with a few percent carbon) at higher initial stellar masses. These stella…
The PDS 110 observing campaign - photometric and spectroscopic observations reveal eclipses are aperiodic
Hugh P. Osborn, Matthew Kenworthy, Joseph E. Rodriguez +71
PDS 110 is a young disk-hosting star in the Orion OB1A association. Two dimming events of similar depth and duration were seen in 2008 (WASP) and 2011 (KELT), consistent with an ob…
