Abstract

Rapid oscillations with a 9-min period have been discovered in the southern Ap SrEu (Cr) star HD 119027. We present Johnson B high-speed photometric observations acquired on 18 nights during 1991 March-June. On some nights, as many as four oscillation modes were excited to observable amplitudes. Detailed frequency analyses reveal the presence of at least five oscillation frequencies in the region of 1.9 mHz with a roughly equal spacing of 26 μHz. However, the data cannot be adequately described with only these five frequencies. Further frequency components are required and those frequencies depend on the particular subset of data being analysed
