Scientific paper

We report the serendipitous discovery of the Sloan Digital Sky Survey star SDSS J160043.6+074802.9 to be a very rapid pulsator. The variation is dominated by a frequency near 8380 μHz (period = 119.33 s) with a large amplitude (0.04 mag) and its first harmonic at 16760 μHz (59.66 s; 0.005 mag). In between these frequencies, we find at least another eight modulations with periods between 62 and 118 seconds and amplitudes between about 0.007 and 0.003 mag. Preliminary spectra from the performance verification phase of the Southern African Large Telescope indicate that SDSS J160043.6+074802.9 is a spectroscopic binary consisting of a subdwarf O star (sdO) and a late-type main-sequence companion.
