Our longest uninterrupted light curve, 9.0 days in length, evidences coherent difference frequencies at periods inaccessible from the ground, up to 14.5 hr, the longest - period signals ever detected in
a pulsating white dwarf.
Our longest... ▽ More We present a preliminary analysis of the cool
pulsating white dwarf GD 1212, enabled by more than 11.5 days of space - based photometry obtained during an engineering test of the two - reaction - wheel - controlled Kepler spacecraft.
A large oxygen - dominated core from the seismic cartography of
a pulsating white dwarf.
