abstract: Kepler Observations of White Dwarfs (J. B. Holberg) (Lunar and Planetary Laboratory, University of Arizona) The faint white dwarf BOKS 53836 was observed in short cadence mode by the Kepler Mission in mid-2009 for 90 days. Analysis of these observations reveals a highly stable photometric modulation with a 3.48 percent half-amplitude and a period of 6.138 hours. Power spectra show only single fundamental frequency and three harmonics, with no significant power at other frequencies. The folded light curve displays an unusual non-sinusoidal shape that is not id difficult to explain in terms of white dwarf spin or a binary system containing an unseen companion. Recent observations with the NOAO Mayall 4-m telescope show a hot DA white dwarf with no obvious signs of Zeeman splitting or an early M-star companion. Kepler observations of other non-variable white dwarfs will be discussed.
