K2 & K1 Precision asteroseismology of hot horizontal branch (subdwarf B) stars
Abstract
During the K2 mission, our collaboration has received data on over 170 hot horizontal branch (subdwarf B) stars. These data have resulted in the discovery of over 50 new pulsators and the first space-based data on several known pulsators. These long continuous data sets, combined with the multi-year K1 mission data, allow precision asteroseismology which provides mode identifications and reveals internal structure. I will review some of our more interesting discoveries and their interpretations.
