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...
A PRECISE ASTEROSEISMIC AGE AND RADIUS FOR THE EVOLVED SUN-LIKE STAR KIC 11026764
Metcalfe, TS; Monteiro, MJPFG; Thompson, MJ; Molenda Zakowicz, J; Appourchaux, T; Chaplin, WJ; Dogan, G; Eggenberger, P; Bedding, TR; Bruntt, HThe primary science goal of the Kepler Mission is to provide a census of exoplanets in the solar neighborhood, including the identification and characterization of habitable Earth-like planets. The asteroseismic capabilities of the mission are being used to determine precise radii and ages for the target stars from their solar-like oscillations. Chaplin et al. published observations of three bright G-type stars...
