Period changes of high-amplitude delta Scuti stars
Abstract
The period changes and stellar evolution of delta Scuti stars are briefly overviewed. The long term behaviour of RV Arietis is discussed. The amplitudes have not changed significantly during the past five decades. The star's fundamental period decreased very slowly.
