-
We report the discovery of oscillations in the hot subdwarf B (sdB) star JL 166 from time-series photometry using the Goodman Spectrograph on the 4.1 m Southern Astrophysical Research Telescope. Previous spectroscopic and photometric observations place the star near the hot end of the empirical sdB instability strip and imply the presence of a cool companion. Amplitude spectra of the stellar light curve reveal at least 10 independent pulsation modes with periods ranging from 97 to 178 s and a...
