I Spy Transits and Pulsations: Empirical Variability in White Dwarfs Using Gaia and the Zwicky Transient Facility
Joseph A. Guidry, Zachary P. Vanderbosch, J. J. Hermes +13
We present a novel method to detect variable astrophysical objects and transient phenomena using anomalous excess scatter in repeated measurements from public catalogs of Gaia DR2…
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…
