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 \(\Delta m=0\overset{\textrm{m}}{.}056{-}0\overset{\textrm{m}}{.}173\) and
periods \(P=18\overset{\textrm{h}}{.}8{-}8\overset{\textrm{d}}{.}3\) were
detected in
\(m=14\overset{\textrm{m}}{.}3\)–\(18\overset{\textrm{m}}{.}8\)
stars. All the stars considered are dwarfs with radii \(R_{*}=0.4{-}0.6R_{\odot}\) (with an uncertainty of up to
\(1.1 R_{\odot}\) 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.
