Query: Solar-Like Oscillations in beta Hydri: Evidence for Short-Lived
  High-Amplitude Oscillations   Velocity measurements of the G2 subgiant beta Hyi with both UCLES and CORALIE
show a clear excess of power centred at 1.0 mHz. In the UCLES data we find
evidence for a short-lived, high-amplitude oscillation event. If confirmed as a
feature of subgiants, such `starquakes' would make it harder to measure
accurate mode frequencies and perform asteroseismology.
