Abstract: We report eight new exoplanet candidates discovered at the Special Astrophysical Observatory of the Russian Academy of Sciences using the transit technique. Photometric observations were performed with a 50-cm robotic telescope during the second half of 2020. Transits with depths of and periods were detected in – stars. All the stars considered are dwarfs with radii (with an uncertainty of up to for a single star). We use simulations to estimate the candidate radii (all are greater than 1.4 times the Jovian radius), semi-major axes of their orbits (0.012–0.035 AU), and other orbital parameters. We report the transit light curves for two stars obtained in 2022 based on individual observations. [ABSTRACT FROM AUTHOR]
