CARMENES. I. A radial-velocity survey for terrestrial planets in the habitable zones of M dwarfs. A historical overview
P. J. Amado, A. Quirrenbach, I. Ribas +7
CARMENES (Calar Alto high-Resolution search for M dwarfs with Exo-earths with Near-infrared and optical Echelle Spectrographs) is a next generation instrument being built for the 3…
MOST observations of the Herbig Ae δ-Scuti star HD 34282
M. P. Casey, K. Zwintz, D. B. Guenther +10
MOST observations and model analysis of the Herbig Ae star HD 34282 (V1366 Ori) reveal δ-Scuti pulsations. 22 frequencies are observed, 10 of which confirm those previously identif…
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…
New ground-based observational methods and instrumentation for asteroseismology
Pedro J. Amado
Space instrumentation like SOHO, MOST, CoRoT and Kepler has been and is being built to attain very high precision data to be used for asteroseismic analysis. Nonetheless, there is…
