The CoRoT B-type binary HD50230: a prototypical hybrid pulsator with g-mode period and p-mode frequency spacings
P. Degroote, C. Aerts, E. Michel +14
B-type stars are promising targets for asteroseismic modelling, since their frequency spectrum is relatively simple. We deduce and summarise observational constraints for the hybri…
Pulsation spectrum of Delta Sct stars: the binary HD 50870 as seen with CoRoT and HARPS
L. Mantegazza, E. Poretti, E. Michel +14
We present the results obtained with the CoRoT satellite for HD 50870, a Delta Sct star which was observed for 114.4 d. The 307,570 CoRoT datapoints were analysed with different te…
The spectroscopic observations of CoRoT asteroseismic targets with HARPS
Ennio Poretti, Monica Rainer, Luciano Mantegazza +6
CoRoT photometric measurements of asteroseismic targets need complementary ground-based spectroscopic observations. We are using the planet-hunter HARPS spectrograph attached to th…
