We present a refined speckle-interferometric orbit of a binary system $\mu$ Cet, with the main component studied based on the analysis of photometric and spectroscopic data, obtained at the SAO RAS 6-m telescope. The object was initially classified a

Searching for Earth-sized planets in data from Kepler's extended mission (K2) is a niche that still remains to be fully exploited. The TFAW survey is an ongoing project that aims to re-analyze all light curves in K2 C1-C8 and C12-C18 campaigns with a

We announce the discovery of GPX-1 b, a transiting brown dwarf with a mass of $19.7\pm 1.6$ $M_{\mathrm{Jup}}$ and a radius of $1.47\pm0.10$ $R_{\mathrm{Jup}}$, the first sub-stellar object discovered by the Galactic Plane eXoplanet (GPX) survey. The

The results of the study of the binary HIP 18856 and construction of its orbit are presented. New observational data obtained at the BTA of SAO RAS in 2007-2019. Earlier Cvetkovi'c et al. (2016) constructed orbit for this system. However, it is based

HIP 53731 is a binary consisting of stars of the spectral types K0 and K9. Orbit of this object was constructed previously by Cvetkovi'c et al. (2016) and improved by Tokovinin (2019). It should be noted that there is an 180 degree ambiguity in the p

We report the first-time use of the Aqueye+ and Iqueye instruments to record lunar occultation events. High-time resolution recordings in different filters have been acquired for several occultations taken from January 2016 through January 2018 with
