Exoplanet Transit Photometry for TESS Planetary Candidates TOI-4439.01 & TOI-5278.01
[Code]
[Paper]
The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission led by MIT and NASA in search of exoplanets. A certain number of planet candidates (PC) discovered by TESS are not actual transiting exoplanets, which are usually referred as "false positives", therefore follow-up ground-based photometry is performed for verifications. We conduct ground-based transit photometry on two planets candidates declared in TESS, TOI-5278.01 and TOI-4439.01 with an 80cm telescope at Xinglong Observatory, P.R. China. Our data processing pipeline comprises of three parts: image reduction, aperture photometry and EXOFAST fit. For TOI-4439.01, our result is in accordance with TESS data, proving the exoplanet nature, while the EXOFAST fit did not converge for TOI-5278.01 due to low SNR of the light curve.
