On the period changes of RR Lyrae variables in the globular cluster M3 |
|
| Authors: | W Wenzel |
| Abstract: | O – C diagrams of 78 RR Lyrae variables of the years 1963 to 1978 were used to investigate their comparability with the diagrams of 1895 to 1963. Only 5% have been proved to show a fundamentally deviating trend of the period change. |
