K. Szatmary et al., APPLICATION OF WAVELET ANALYSIS IN VARIABLE-STAR RESEARCH .2. THE SEMIREGULAR STAR V-BOOTIS, Astronomy and astrophysics, 308(3), 1996, pp. 791-798
Light curve analysis of the SRa-type variable V Boo is presented and d
iscussed. The periods are determined and the stability of these period
s 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 theoreti
cal models and observational relations physical parameters and pulsati
onal modes of V Boo are also estimated.
