Analyse photometrischer Beobachtungen des Doppelmoden-Pulsationssterns EW Scuti.
Abstract
The variable EW Sct has been investigated by means of photographic observations mainly on plates of the Sonneberg Sky Patrol. The double mode behaviour has been confirmed and analysed. The authors estimated the long-term elements of the two pulsation modes and the corresponding beat period. The star shows clear variations particularly of the phases and the period of the first overtone.
