Binarity and multiperiodicity in high-amplitude δ Scuti stars
Binarity and multiperiodicity in high-amplitude δ Scuti stars
We have carried out a photometric and spectroscopic survey of bright high-amplitude δ Scuti (HADS) stars. The aim was to detect binarity and multiperiodicity (or both) in order to explore the possibility of combining binary star astrophysics with stellar oscillations. Here, we present the first results for 10, predominantly southern, …
