Light Curve Modelling and Evolutionary Status of the Short Period Binary 1SWASP J092328.76+435044

TL;DR

This study models the light curves of the short-period binary 1SWASP J092328.76+435044 using new BVR data, revealing temperature differences and evolutionary status of the components.

Contribution

It introduces a new light curve analysis of the system with a spotted model and estimates physical parameters and evolutionary state.

Findings

Massive component is hotter by about 400K.

Eight new times of minima were determined.

The evolutionary status of the components was assessed.

Abstract

Light curve modeling for the newly discovered system 1SWASP J092328.76+435044 was carried out by using a new BVR complete light curves. A spotted model was applied to treat the asymmetry of the light curves. The output model was obtained by means of Wilson-Devinney code, which reveals that the massive component is hotter than the less massive one with about \Delta T ~ 400K. A total of 8 new times of minima were estimated. The evolutionary state of the system components was investigated based on the estimated physical parameters.
