The all-sky GEOS RR Lyr survey with the TAROT telescopes. Analysis of the Blazhko effect
J. -F. Le Borgne, A. Klotz, E. Poretti +9
We used the GEOS database to study the Blazhko effect of galactic RRab stars. The database is continuously enriched by maxima supplied by amateur astronomers and by a dedicated sur…
CoRoT observations of O stars: diverse origins of variability
R. Blomme, M. Briquet, P. Degroote +26
Six O-type stars were observed continuously by the CoRoT satellite during a 34.3-day run. The unprecedented quality of the data allows us to detect even low-amplitude stellar pulsa…
Fourier analysis of non-Blazhko ab-type RR Lyrae stars observed with the Kepler space telescope
J. M. Nemec, R. Smolec, J. M. Benko +22
Nineteen of the ~40 RR Lyr stars in the Kepler field have been identified as candidate non-Blazhko (or unmodulated) stars. In this paper we present the results of Fourier decomposi…
Stellar evolution in real time: Period variations in galactic RR Lyr stars
E. Poretti, J. F. Le Borgne, J. Vandenbroere +6
The times of maximum brightness collected in the GEOS RR Lyr database allowed us to trace the period variations of a sample of 123 galactic RRab variables. These data span a time b…
CoRoT and asteroseismology. Preparatory work and simultaneous ground-based monitoring
Ennio Poretti, Monica Rainer, Katrien Uytterhoeven +3
The successful launch of the CoRoT (COnvection, ROtation and planetary Transits) satellite opens a new era in asteroseismology. The space photometry is complemented by high-resolut…
Preparing the COROT space mission: new variable stars in the galactic Anticenter direction
E. Poretti, R. Alonso, P. J. Amado +15
The activities related to the preparation of the asteroseismic, photometric space mission COROT are described. Photoelectric observations, wide--field CCD photometry, uvbyB calibra…
