Oscillation mode lifetimes in ksi Hydrae: Will strong mode damping limit asteroseismology of red giant stars?

D. Stello, H. Kjeldsen, T. R. Bedding +1

We introduce a new method to measure frequency separations and mode lifetimes of stochastically excited and damped oscillations, so-called solar-like oscillations. Our method shows…

Observing solar-like oscillations: recent results

Timothy R. Bedding, Hans Kjeldsen

We review recent progress in observations of ground-based oscillations. Excellent observations now exist for a few stars (alpha Cen A and B, mu Ara), while there is some controvers…

Solar-like oscillations in alpha Centauri B

Hans Kjeldsen, Timothy R. Bedding, R. Paul Butler +6

We have made velocity observations of the star alpha Cen B from two sites, allowing us to identify 37 oscillation modes with l=0-3. Fitting to these modes gives the large and small…

The light curve of the semiregular variable L2 Puppis: II. Evidence for solar-like excitation of the oscillations

T. R. Bedding, L. L. Kiss, H. Kjeldsen +4

We analyse visual observations of the pulsations of the red giant variable L2 Pup. The data cover 77 years between 1927 and 2005, thus providing an extensive empirical base for cha…

Evidence for Granulation and Oscillations in Procyon from Photometry with the WIRE satellite

H. Bruntt, H. Kjeldsen, D. L. Buzasi +1

We report evidence for the granulation signal in the star Procyon A, based on two photometric time series from the star tracker on the WIRE satellite. The power spectra show eviden…

Red variables in the OGLE-II data base -- III. Constraints on the three-dimensional structures of the LMC and SMC

P. Lah, L. L. Kiss, T. R. Bedding

We present an analysis of the 3-D structure of the Magellanic Clouds, using period-luminosity (P-L) relations of pulsating red giants in the OGLE-II sample. By interpreting deviati…
