First photometric investigation of some ASAS binary systems

TL;DR

This paper presents the first light curve analyses of four binary star systems from the ASAS survey using PHOEBE software, deriving their physical parameters and evolutionary states.

Contribution

It provides the initial photometric solutions for these binaries and compares their properties with known systems, enhancing understanding of their evolution.

Findings

Derived physical parameters for four binary systems.

Compared these systems to similar known binaries.

Discussed the evolutionary states of the components.

Abstract

We present the first light curve solutions of the four binary systems observed and catalogued by the All Sky Automated Survey program. The light curves are analysed by using PHOEBE software, which is based on the Wilson-Devinney method. The light curve parameters are derived and the estimated physical parameters are calculated from the result of the analyses. We compare our targets to well-known binaries of similar type on the Hertzsprung-Russell diagram and mass-radius plane. The evolutionary states of the components are also discussed.
