The data mining: An analysis of 20 eclipsing binary light-curves observed by the INTEGRAL/OMC

TL;DR

This study analyzes 20 neglected eclipsing binary light-curves from the INTEGRAL/OMC database, providing initial insights into their properties and discovering ET Vel as an eccentric system, highlighting the need for further spectroscopic research.

Contribution

First light-curve analysis of 20 eclipsing binaries from INTEGRAL/OMC, identifying ET Vel as eccentric and emphasizing the importance of spectroscopic follow-up.

Findings

Most systems are detached binaries.

ET Vel is an eccentric binary.

Further spectroscopic studies are needed.

Abstract

Twenty eclipsing binaries were selected for an analysis from a huge database of observations made by the INTEGRAL/OMC camera. The photometric data were processed and analyzed, resulting in a first light-curve study of these neglected eclipsing binaries. Most of the selected systems are the detached ones. The system ET Vel was discovered to be an eccentric one. Due to missing spectroscopic study of these stars, further detailed analyses are still needed.
