Abstract

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 1452 μHz. However, these frequency values suffer from 1 d-1 alias ambiguities, and require confirmation in a more detailed follow-up study.
