The Pulsating Helium-Atmosphere White Dwarfs I: New DBVs from the Sloan Digital Sky Survey
Zachary P. Vanderbosch, J. J. Hermes, Don E. Winget +4
We present a dedicated search for new pulsating helium-atmosphere (DBV) white dwarfs from the Sloan Digital Sky Survey using the McDonald 2.1m Otto Struve Telescope. In total we ob…
Identifying Periodic Variable Stars and Eclipsing Binary Systems with Long-Term Las Cumbres Observatory Photometric Monitoring of ZTF J0139+5245
Aniket Sanghi, Zachary P. Vanderbosch, Michael H. Montgomery
We present the results of our search for variable stars using the long-term Las Cumbres Observatory (LCO) monitoring of white dwarf ZTF J0139+5245 with the two 1.0-m telescope node…
Recurring Planetary Debris Transits and Circumstellar Gas around White Dwarf ZTF J03281219
Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry +14
We present follow-up photometry and spectroscopy of ZTF J03281219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transie…
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…
