Discovery, TESS Characterization, and Modeling of Pulsations in the Extremely Low Mass White Dwarf GD 278

Isaac D. Lopez, J. J. Hermes, Leila M. Calcaferro +5

We report the discovery of pulsations in the extremely low mass (ELM), likely helium-core white dwarf GD 278 via ground- and space-based photometry. GD 278 was observed by the Tran…

EPIC 228782059: Asteroseismology of what could be the coolest pulsating helium-atmosphere white dwarf (DBV) known?

R. M. Duan, W. Zong, J. -N. Fu +5

We present analysis of a new pulsating helium-atmosphere (DB) white dwarf, EPIC~228782059, discovered from 55.1~days of {\em K2} photometry. The long duration, high quality light c…

The Heating and Pulsations of V386 Serpentis after its 2019 Dwarf Nova Outburst

Paula Szkody, Patrick Godon, Boris T. Gaensicke +10

Following the pulsation spectrum of a white dwarf through the heating and cooling involved in a dwarf nova outburst cycle provides a unique view of the changes to convective drivin…
