Photometric study of an Eclipsing Binary in Praesepe

TL;DR

This study provides detailed CCD photometric observations and analysis of an eclipsing binary in Praesepe, revealing it as a W-type W UMa system with parameters similar to SW Lac.

Contribution

First detailed photometric analysis of this eclipsing binary, confirming its classification as a W-type W UMa system and comparing its parameters to a known contact binary.

Findings

System classified as W-type W UMa contact binary

System parameters similar to SW Lac

Detailed photometric solutions obtained using Wilson-Devinney code

Abstract

We present CCD photometric observations of an eclipsing binary in the direction of the open cluster Praesepe using the 2 m telescope of IUCAA Girawali Observatory, India. Though the system was classified as an eclipsing binary by Pepper et al.(2008),detail investigations were lacking. The photometric solutions using the Wilson-Devinney code suggest that it is a W-type W UMa system and interestingly, the system parameters were similar to another contact binary system SW Lac.
