Long-term photometric monitoring of RR Lyrae stars in Messier 3

The period-change behaviour of 134 RR Lyrae stars in the globular cluster Messier 3 (M3) is investigated on the ∼120 yr time-base of the photometric observations. The mean period-change rates (β≈ 0.01 d Myr−1) of the subsamples of variables exhibiting the most regular behaviour are in good agreement...
