Abstract
The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. During its first two years in orbit, the TESS spacecraft concentrated its gaze on several hundred thousand specially chosen stars, looking for small dips in their light caused by orbiting planets passing between their host star and us. Because of the low spatial resolution of its cameras, TESS is expected to detect several false positives (FPs). It can identify as NEB (Nearby Eclipsing Binary), BEB (Blended Eclipsing Binary) or EB (Eclipsing Binary).We use AIJ(AstroImageJ) to find the TOI 4620.01 and create the lightcurve. We found that the brightness of the planet tends to decrease around the predicted time. After that we identify there is a transit.
