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…
