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…
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…
WD1032+011, an inflated brown dwarf in an old eclipsing binary with a white dwarf
S. L. Casewell, C. Belardi, S. G. Parsons +11
We present the discovery of only the third brown dwarf known to eclipse a non-accreting white dwarf. Gaia parallax information and multi-colour photometry confirm that the white dw…
The McDonald Observatory search for pulsating sdA stars: asteroseismic support for multiple populations
Keaton J. Bell, Ingrid Pelisoli, S. O. Kepler +8
Context. The nature of the recently identified "sdA" spectroscopic class of star is not well understood. The thousands of known sdAs have H-dominated spectra, spectroscopic surface…
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…
