A new large-amplitude slowly pulsating sdB star

Abstract

We report the discovery of a new large-amplitude slowly pulsating sdB star, EC 21324-1346. Although we have only a small amount of data, it is clear that the star exhibits more than one mode of variation; the present data can be adequately represented with three or four frequencies in the range 170-330 μHz (about 0.8 to 1.6 hours). The amplitude of the dominant frequency is about 0.004 mag - large for a slowly pulsating sdB star.
