The data mining III: An analysis of 21 eclipsing binary light-curves observed by the INTEGRAL/OMC

TL;DR

This study analyzes 21 eclipsing binary light-curves from the INTEGRAL/OMC database, confirming and refining orbital periods, and deriving new minima times, providing the first detailed light-curve analysis of these neglected systems.

Contribution

It presents the first light-curve analysis of 21 neglected eclipsing binaries and updates their orbital periods based on new photometric data.

Findings

Confirmed or modified orbital periods for several systems

Derived 32 new minima times

Provided the first detailed light-curve analysis of these binaries

Abstract

Twenty-one 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. In several systems from this sample even their orbital periods have been confirmed or modified. Thirty-two new minima times of these binaries have been derived.
