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…
Pulsation in the white dwarf HE 1017-1352: confirmation of the class of hot DAV stars
Alejandra D. Romero, L. Antunes Amaral, S. O. Kepler +3
We report the detection of periodic variations on the T_eff ~32 000 K DA white dwarf star HE 1017-1352. We obtained time series photometry using the 4.1 m SOAR telescope on three s…
Evidence of Spectral Evolution on the white dwarf sample from the Gaia Mission
G. Ourique, S. O. Kepler, A. D. Romero +2
Since the Gaia data release 2, several works were published describing a bifurcation in the observed white dwarf colourmagnitude diagram for $\mbox{$G_{\mathrm{BP}}$}-\mbox{$G_{…
