Ensemble Asteroseismology of Solar-Type Stars with the NASA Kepler Mission
Chaplin, WJ; Kjeldsen, H; Christensen Dalsgaard, J; Basu, S; Miglio, A; Appourchaux, T; Bedding, TR; Elsworth, Y; Garcia, RA; Gilliland, RL; Girardi, LIn addition to its search for extrasolar planets, the NASA Kepler mission provides exquisite data on stellar oscillations. We report the detections of oscillations in 500 solar-type stars in the Kepler field of view, an ensemble that is large enough to allow statistical studies of intrinsic stellar properties (such as mass, radius, and age) and to test theories of stellar evolution. We find that the distributio...
THE ASTEROSEISMIC POTENTIAL OF KEPLER: FIRST RESULTS FOR SOLAR-TYPE STARS
Chaplin, WJ; Appourchaux, T; Elsworth, Y; Garcia, RA; Houdek, G; Karoff, C; Metcalfe, TS; Molenda Zakowicz, J; Monteiro, MJPFG; Thompson, MJ; Brown, TMWe present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5 days of science operations, reveal high signal-to-noise solar-like oscillation spectra in all three stars: about 20 modes of oscillation may be clearly distinguished in each star. We discuss the appearance of the oscillation spectra, use the frequencies and frequency...
