Journal ArticleDOI
Detection of Solar-like Oscillations in the G7 Giant Star xi Hya
S. Frandsen,Fabien Carrier,Conny Aerts,Dennis Stello,T. Maas,M. Burnet. H. Bruntt,Teresa C. Teixeira,J. R. De Medeiros,François Bouchy,H. Kjeldsen,Frank P. Pijpers,Jørgen Christensen-Dalsgaard +11 more
TL;DR: In this article, the discovery of solar-like oscillations in a giant star was confirmed by using the CORALIE spectrograph attached to the 1.2m Swiss Euler telescope.
Journal ArticleDOI
Solar-like Oscillations in the G2 Subgiant β Hydri from Dual-Site Observations
Timothy R. Bedding,Hans Kjeldsen,Torben Arentoft,François Bouchy,Jacob Brandbyge,Brendon J. Brewer,R. Paul Butler,Jørgen Christensen-Dalsgaard,T. H. Dall,Søren Frandsen,Christoffer Karoff,László L. Kiss,Mário J. P. F. G. Monteiro,Frank P. Pijpers,Teresa C. Teixeira,C. G. Tinney,Ivan K. Baldry,Fabien Carrier,Simon J. O'Toole +18 more
TL;DR: In this paper, the HARPS and UCLES spectrographs were combined with those obtained five years earlier to identify 28 oscillation modes, and a detailed comparison of the mixed l ¼ 1 modes with theoretical models should allow a precise estimate of the age of the star.
Journal ArticleDOI
Solar-like oscillations in the G2 subgiant beta Hydri from dual-site observations
Timothy R. Bedding,Hans Kjeldsen,Torben Arentoft,François Bouchy,Jacob Brandbyge,Brendon J. Brewer,R. Paul Butler,Joergen Christensen-Dalsgaard,T. H. Dall,S. Frandsen,Christoffer Karoff,László L. Kiss,Mário J. P. F. G. Monteiro,Frank P. Pijpers,Teresa C. Teixeira,C. G. Tinney,Ivan K. Baldry,Fabien Carrier,Simon J. O'Toole +18 more
TL;DR: In this paper, the authors 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 spectrographs.
Journal ArticleDOI
Solar-like oscillations in the G8 V star tau Ceti
Teresa C. Teixeira,H. Kjeldsen,Timothy R. Bedding,François Bouchy,J. Christensen-Dalsgaard,M. S. Cunha,T. H. Dall,S. Frandsen,Christoffer Karoff,Mário J. P. F. G. Monteiro,Frank P. Pijpers +10 more
TL;DR: In this paper, the authors used HARPS to measure oscillations in the low-mass star tau Cet. Although the data were compromised by instrumental noise, they were able to extract the main features of the oscillations.
Journal ArticleDOI
Time-series Spectroscopy of Pulsating sdB Stars: PG1605+072
Simon J. O'Toole,Timothy R. Bedding,H. Kjeldsen,Teresa C. Teixeira,G. Roberts,F. van Wyk,D. Kilkenny,N. D’Cruz,Ivan K. Baldry +8 more
TL;DR: In this article, velocity variations in the pulsating sdB star PG 1605+072 were detected at the same frequencies found from photometry and have amplitudes of up to 14 km/s for H$\beta$.
