Abstract

High-speed multicolor photometry with ULTRACAM promises to revolutionize the study of pulsating subdwarf B stars. As well as providing high SIN light curves with excellent temporal resolution, color amplitude ratios may be used to discriminate between different pulsation modes. In this paper we review the methods for mode determination developed for KPD 2109+4401 and HS 0039+4302 since the 2003 workshop. We also present a new dataset obtained over 6 nights in 2004 August for PG 0014+067. This was the first sdB star to be subjected to a detailed asteroseismological analysis. It was also the subject of the WET campaign in 2004 October/November (XCov24). We discuss the implications of our new observations for mode identification and rotation.
