Discovery of A New Class of Pulsating Stars: Gravity-Mode Pulsators among Subdwarf B Stars
During the course of an ongoing CCD monitoring program to investigate low-level light variations in subdwarf B (sdB) stars, we have serendipitously discovered a new class of low-amplitude, multimode sdB pulsators with periods of the order of an hour. These periods are more than a factor of 10 longer than …
