Abstract:
RR Gem is one of the few Blazhko RR Lyrae which has extended enough
photometric observations available to study the long-term courses of
its pulsation and modulation properties in detail. We investigate the
pulsation and modulation properties and the relations between them in
RR Gem using the last 70 years' photometric observations in order to
gain further insight into the nature of the Blazhko modulation.
Photographic, photoelectric and CCD light curves obtained at the
Konkoly Observatory and other authors' published maxima observations
are studied. Detailed analysis of the light curves, maximum brightness
and O-C data are carried out.
Description:
The observations were obtained with different telescopes of the
Konkoly Observatory with photographic, photoelectric and CCD detectors
between 1935 and 2005.
