Oscillations in alpha Cen A observed with UCLES at the AAT
T. R. Bedding, R. P. Butler, C. McCarthy +5
We report Doppler measurements of alpha Cen A from time-series spectroscopy made with UCLES at the 3.9-m AAT. Wavelength calibration using an iodine absorption cell produced high-p…

Solar-Like Oscillations in beta Hydri: Evidence for Short-Lived High-Amplitude Oscillations
T. R. Bedding, H. Kjeldsen, I. K. Baldry +7
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,…

Optical Spectroscopy of DENIS Mini-survey Brown Dwarf Candidates
C. G. Tinney, X. Delfosse, T. Forveille +1
We present optical (6500-9200A) spectroscopy of eight cool dwarfs detected in a 231 square degree ``Mini-survey'' of the Deep NEar Infrared Survey (DENIS) data. We are able to conf…
