Abstract:
The period-change behaviour of 134 RR Lyrae stars in the globular
cluster Messier 3 (M3) is investigated on the ∼120yr time-base of the
photometric observations. The mean period-change rates
(β≈0.01d/Myr) of the subsamples of variables exhibiting the most
regular behaviour are in good agreement with theoretical expectations
based on horizontal branch stellar evolution models. However, a large
fraction of variables show period changes that contradict the
evolutionary expectations.
Description:
Photographic observations of M3 with the telescopes of the Konkoly
Observatory were obtained after 1962, which data have not been
published previously. The exposures taken without a filter with the
60-cm telescope on two nights in 1964 and 1968, and with the 1-m RCC
telescope between 1976 and 1980, and 1988 and 1989 using 103aO plates
are processed in this work.

Note (1): No O-C solutions are given for the variables denoted by "*"
because of their extremely complex period variations.
Note (2): The pulsation periods given are adopted to construct the O-C plots.
The period is valid for the latest-epoch observations for stars
denoted by "*".
Note (3): The mean magnitude corresponds to the constant term of an
appropriate-order Fourier-series fit of the CCD V data.
Note (4): Full amplitude of the mean light curves of Blazhko stars is
given. No or defective CCD photometry is available for V113, V115,
V123 and V135. AV is estimated from Apg (AV∼AB/1.3).
