Discovery of p-mode oscillations in the Ap star HD 213637.
MARTINEZ P., MEINTJES P., RATCLIFF S.J. and ENGELBRECHT C.
Abstract (from CDS):
We announce the discovery of rapid p-mode oscillations in the A (p EuSrCr) star HD 213637. These variations are modulated in amplitude, which is consistent with rotational modulation, multi-mode oscillations or intrinsic mode growth/decay. A frequency analysis reveals that our data may be described by the combination of two oscillations with frequencies of 1411 and 1452µHz. However, these frequency values suffer from 1d–1 alias ambiguities, and require confirmation in a more detailed follow-up study.
