Solar-like oscillations in the G8 V star tau Ceti
T. C. Teixeira, H. Kjeldsen, T. R. Bedding +8
We used HARPS to measure oscillations in the low-mass star tau Cet. Although the data were compromised by instrumental noise, we have been able to extract the main features of the…
Asteroseismology and Interferometry
M. S. Cunha, C. Aerts, J. Christensen-Dalsgaard +22
Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first systematic studies…
Solar-like oscillations in the G2 subgiant beta Hydri from dual-site observations
Timothy R. Bedding, Hans Kjeldsen, Torben Arentoft +16
We have observed oscillations in the nearby G2 subgiant star beta Hyi using high-precision velocity observations obtained over more than a week with the HARPS and UCLES spectrograp…
Report on the CoRoT Evolution and Seismic Tools Activity
M. K. J. P. F. G. Monteiro, Y. Lebreton, J. Montalban +24
We present the work undertaken by the Evolution and Seismic Tools Activity (ESTA) team of the CoRoT Seismology Working Group. We have focused on two main tasks: Task 1 - now finish…
Time-series Spectroscopy of Pulsating sdB Stars: PG1605+072
S. J. O'Toole, T. R. Bedding, H. Kjeldsen +6
We report the detection of velocity variations in the pulsating sdB star, PG 1605+072. Oscillations are detected at the same frequencies found from photometry and have amplitudes o…
Time-series Spectroscopy of EC14026 Stars: Preliminary Results
Simon J. O'Toole, Teresa C. Teixeira, Timothy R. Bedding +1
We have obtained time-series spectra for the pulsating hot subdwarf (sdB) PG1605+072. Previous time-series photometry of this star has shown maximum amplitude variations of about 0…
