The data mining II: An analysis of 33 eclipsing binary light-curves observed by the INTEGRAL/OMC

TL;DR

This study analyzes 33 neglected eclipsing binary stars observed by INTEGRAL/OMC, providing initial light-curve data, discovering eccentricity in CY Lac, and confirming or refining orbital periods, highlighting the need for further spectroscopic research.

Contribution

First light-curve analysis of 33 neglected eclipsing binaries from INTEGRAL/OMC data, including discovery of eccentricity and period confirmation or modification.

Findings

CY Lac identified as eccentric binary

Orbital periods confirmed or refined for several systems

Initial light-curve data for neglected binaries

Abstract

Thirty-three 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. The system CY Lac was discovered to be an eccentric one. In several systems from this sample even their orbital periods have been confirmed or modified. Due to missing spectroscopic study of these stars, further detailed analyses are still needed.
