Binarity and multiperiodicity in high-amplitude delta Scuti stars
A. Derekas, L. L. Kiss, T. R. Bedding +10
We have carried out a photometric and spectroscopic survey of bright high-amplitude delta Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order…

Pulsation and orbit of AU Pegasi
M. Jurkovic, L. Szabados, J. Vinkó +1
AU Pegasi is a pulsating star in a spectroscopic binary system with an orbital period of 53.26 days. Between 1960 and 1990 an extremely rapid period increase was observed in the va…
