The eclipsing binary system SW Lacertae: hotometric study

TL;DR

This study presents detailed photometric observations and analysis of the eclipsing binary SW Lacertae, determining its period, physical parameters, and system geometry using light curves and the W-D code.

Contribution

It provides new blue and visual light curves and refines the system's physical and geometrical parameters using the Wilson-Devinney code, comparing with recent studies.

Findings

Period of 0.320854 days determined.

System analyzed through ellipsoidal model.

Physical parameters compared with recent data.

Abstract

Blue and Visual photoelectric light curves have been achieved for the eclipsing binary SW Lac in 1995. Nine moments of minimum light were derived. Period of 0.320854 days have been determined as the mean of those derived from blue and visual observations. B and V light curves have been analyzed using W-D code where the system has been viewed through the ellipsoidal model. The system geometrical and physical parameters were determined and compared with those published recently.
