Discovery and Light Curve Analysis of a New Eclipsing Binary Candidate: TIC 121462345

This paper presents the discovery and preliminary light curve analysis of a new eclipsing binary star candidate, designated as TIC 121462345 (Zooniverse Subject 121462345). Utilizing high-cadence photometric data from NASA’s Transiting Exoplanet Survey Satellite (TESS) during Sector 102, a definitive periodic dimming was identified via citizen science inspection on the Planet Hunters TESS platform. The light curve exhibits two sharp, symmetric primary and secondary minimums, reaching down to a relative brightness dip of approximately -0.85, despite notable stellar background noise. The orbital period of the binary system is evaluated to be roughly 13 days. A cross-match query on the SIMBAD astronomical database reveals that while the stellar target is registered, its nature as an eclipsing binary system has not been previously cataloged.
