Abstract

We recently reported strong evidence for solar-like oscillations in the G0 IV star eta Boo (Kjeldsen et al. 1995, AJ 109, 1313). We measured small temperature fluctuations produced by oscillations through their effect on the equivalent widths of the Balmer lines. Here we address several issues that were raised at this conference. In particular, we show a power spectrum made without applying a high-pass filter to the observations. This spectrum shows increased noise at low frequencies, as expected, and the oscillation signature is still clearly visible.
