More new sdB pulsators discovered with the Nordic Optical Telescope.
SOLHEIM J.-E. and OSTENSEN R.
Abstract (from CDS):
We report briefly the results from a continuation of the NOT search program for pulsating sdB stars. During this period we have observed 45 candidates and found three new short period pulsating sdB stars. Two of the new pulsators were selected based on spectroscopy from the Sloan Digital Sky Survey, while the third is a PG object. All the stars have periods in the range 120-140 s, typical for short period subdwarf B pulsators, and the detected pulsation amplitudes are all relatively low, between 0.3 and 0.7%.
