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…
Evolutionary changes in the periods of galactic RRab stars
Jacqueline Vandenbroere, Ennio Poretti, Jean-Francois Le Borgne
Le Borgne et al. (2007) report on the determination of evolutionary changes in the periods of field RR Lyr stars. Thanks to the extension of the GEOS database, we could analyze a s…
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…
Stellar evolution through the ages: period variations in galactic RRab stars as derived from the GEOS database and TAROT telescopes
J. F. Le Borgne, A. Paschke, J. Vandenbroere +6
The theory of stellar evolution can be more closely tested if we have the opportunity to measure new quantities. Nowadays, observations of galactic RR Lyr stars are available on a…
