Catalogue and properties of δ Scuti stars in binaries

The catalogue contains 199 confirmed cases of binary systems containing at least one pulsating component of ... Sct type. The sample is divided into subgroups in order to describe the properties and characteristics of the ... Sct-type stars in binaries according to their Roche geometry. Demographics describing quantitatively our knowledge for these systems as well as the distributions of their pulsating components in the mass-radius, colour-magnitude, and evolutionary status-temperature diagrams are presented and discussed. It is shown that a threshold of ~13 d of the orbital period regarding the influence of binarity on the pulsations is established. Finally, the correlations between the pulsation periods and the orbital periods, evolutionary status, and companion's gravity influence are updated based on the largest sample to date.
