Multi‐Stage Vetting and Photometric Modeling of the Sub‐Giant/M‐Dwarf Binary TIC 262010525

ABSTRACT The eclipsing binary system TIC 262010525 is characterized through an integrated analysis of TESS photometric data and Gaia DR3 astrometric constraints. To ensure the reliability of the system as a detached eclipsing binary, a multi‐stage vetting process is performed, utilizing the Triceratops framework to evaluate potential false positive scenarios, even‐odd transit depth analysis to confirm the orbital period, and centroid vetting to exclude background contaminants. Synthetic light curves are generated using the PHOEBE modeling framework, and the parameter space is explored via MCMC simulations. An independent broadband SED analysis yields an exceptional fit () across optical to mid‐infrared passbands, confirming the stellar parameters and the absence of infrared excess. The convergence of the MCMC chains and the mapping of parameter degeneracies are validated through posterior distribution analysis, where high‐density contour centroids are observed to align with the calculated median values. By fixing the primary radius () to Gaia DR3 measurements, physical discrepancies previously identified in catalogs such as ExoFOP are resolved, yielding a reconciled model of a sub‐giant primary with a low‐mass M‐dwarf companion.
