Abstract

Light curve analysis of the SRa-type variable V Boo is presented and discussed. The periods are determined and the stability of these periods as well as their amplitudes are investigated with wavelet analysis. The amplitude decrease is studied with the so called ridge procedure, which shows that the amplitude of the longer period strongly decreased while the amplitude of the shorter period seems to remain stable. The possible interpretations of this effect are discussed. Using theoretical models and observational relations physical parameters and pulsational modes of V Boo are also estimated.
