Observational Evidence of Convective Cycles as the Cause of the Blazhko Effect in RR Lyrae Stars
Abstract
Among RR Lyrae stars displaying the Blazhko effect, a few show no period modulation in spite of striking changes in their light amplitudes. This anomalous behavior and the mean period of the affected variables are predicted correctly by the theory of slow convective cycles in the stellar envelope.
