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 .
We detect at least 19 independent pulsation modes , ranging from 828.2 - 1220.8 s , and at least 17 nonlinear combination frequencies of those independent pulsations .
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 .
These results mark some of the first science to come from a two-wheel-controlled Kepler spacecraft , proving the capability for unprecedented discoveries afforded by extending Kepler observations to the ecliptic .
