First Light Curve Analyses of Binary Systems AO Aqr, CW Aqr and ASAS 012206-4924.7

TL;DR

This study presents the first light curve analyses of three eclipsing binary systems using ASAS data, determining their physical parameters and classifications, and discussing their positions in the HR diagram.

Contribution

First light curve analyses of AO Aqr, CW Aqr, and ASAS 012206-4924.7 using ASAS data and PHOEBE software, classifying their binary types and discussing stellar parameters.

Findings

AO Aqr is a contact binary.

CW Aqr is a near-contact binary.

ASAS 012206-4924.7 is a detached binary.

Abstract

Using the data from the public database of the All Sky Automated Survey ({\tt ASAS}) we performed the very first light curve analyses of the three eclipsing binary systems \astrobj{AO~Aqr}, \astrobj{CW~Aqr} and \astrobj{ASAS~012206-4924.7}. The physical parameters of the systems were determined by the {\tt PHOEBE} software. From an analysis of the ASAS data it was concluded that AO~Aqr was found to be a contact binary system while CW~Aqr and ASAS~012206-4924.7 were found to be near--contact and detached binaries, respectively. Finally, the locations of the components, corresponding to the estimated physical parameters, in the HR diagram were also discussed.
