Classification of eclipsing binaries: attractive systems

TL;DR

This paper presents a comprehensive catalogue of eclipsing binary stars, a classification procedure based on catalogued data, and discusses unclassified systems requiring further observations.

Contribution

It introduces the largest catalogue of eclipsing binaries and a new classification method applied to unclassified systems, highlighting cases needing additional data.

Findings

Largest catalogue of eclipsing binaries compiled

New classification procedure developed and applied

Identification of systems requiring further observations

Abstract

We have compiled a catalogue of eclipsing variable stars, the largest catalogue, containing classified eclipsing binaries. A procedure for the classification of eclipsing binaries, based on the catalogued data, is also developed. It was applied to unclassified eclipsing binaries. In this paper we discuss eclipsing binaries, which can not be classified with the procedure. Some of them belong to marginal evolutionary classes. Observational data for others are too contradictory, and additional observations are needed to attribute them to one or another evolutionary class.
