S. N. Udovichenko, L. E. Keir

Анотація


The photometric observations for the RR Lyr-type star AE Leo in the Astronomical station near Odessa using the 48-cm reflector AZT-3 and the CCD photometer equipped with the V filter have been carried out. The light curves shows variable amplitude of light maxima and the moderate Blazhko effect. The analysis of the O-C light maxima for our observations and the ASAS, NSVS data indicates the secular period changes.
