Binaries with a $\delta$ Scuti component: Results from a long term observational survey, updated catalogue and future prospects

TL;DR

This paper reports on a six-year observational survey of eclipsing binaries with δ Scuti pulsating components, discovering new systems, updating the catalog, and exploring correlations between pulsation and binarity.

Contribution

It provides the first extensive survey results, an updated catalog of δ Scuti binaries, and discusses potential correlations between pulsational and binary properties.

Findings

Discovered 13 new δ Scuti binary systems.

Updated the catalog with all known systems of this type.

Identified potential correlations between pulsation and binarity.

Abstract

Results from a six year systematic observational survey on candidate eclipsing binaries with a $\delta$ delta Sct component are presented. More than a hundred systems with component(s) of A-F spectral types were observed in the frame of this survey in order to be checked for possible pulsational behaviour. The 14% (13 cases) of the currently known such systems were discovered during this survey. Using all the available information from the literature, an updated list with all the currently known systems of this type is presented, while possible correlations between their pulsational and binarity properties are discussed.
