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…

Gravitational Influence from Planets on the Measured Rates of Period Change of Pulsating White Dwarfs
Ling Xuan Yao, Keaton J. Bell, Andrew Dublin
The measured rates of period change, , in the signals of pulsating white dwarf stars are often interpreted as direct detections of structural changes from secular cooling.…

White Dwarf Variability
Keaton J. Bell
There are a few different mechanisms that can cause white dwarf stars to vary in brightness, providing opportunities to probe the physics, structures, and formation of these compac…
