Abstract
In this paper, we present a comprehensive analysis and validation of four exoplanet candidates, TOI-1001.01, TOI-1007.01, TOI-1019.01 and TOI-1032.01 selected from the NASA Exoplanet Archive. We use data from Transiting Exoplanet Survey Satellite (TESS) and apply the transit method to identify periodic dimming events, which are indicative of planetary transits. To obtain the best-fit and de-trended fluxes for our objects we used the the box-least squares (BLS) models. In addition, we performed odd-even transit and background-flux analysis for the further validation of candidates as true exoplanets.
