Four New Eclipsing Binary Systems in the TESS field: CD-34 13220, HD 295082, TYC 6484-426-1 and TYC 6527-2310-1

TL;DR

This study identifies four new eclipsing detached binary systems in the TESS field, analyzing their light curves, orbital parameters, and evolutionary states to expand understanding of such systems.

Contribution

First evidence of binarity for these four targets, with detailed analysis of their orbital and physical parameters using TESS data and SED analysis.

Findings

All four systems are eclipsing detached binaries.

Orbital periods and absolute parameters were successfully derived.

Comparison with similar systems suggests their evolutionary stages.

Abstract

We present the first evidence for the binarity of four targets in the TESS field. The temperatures are estimated by SED analysis and the orbital periods are determined. The TESS light curves of the systems are analysed and the orbital and the absolute parameters are derived. The targets are also compared to well-studied binary systems with the same morphological type and their evolutionary states are discussed. Our results indicate that the stars belong to the class of eclipsing detached binary systems.
