We present the results of a UBVRcIc and JHKLM photometric monitoring campaign conducted in 2016–2020, low-resolution spectroscopy, and an analysis of the ASAS-3 and ASAS-SN photometric data for the semiregular variable and post-AGB candidate AU Vul

For both periods of the double-mode classical Cepheid AS Cas we have constructed $$O-C$$ diagrams spanning a time interval of 132 years. The $$O-C$$ diagrams have the shape of parabolas, which has allowed us for the first time to determine the quadra

We present results from multiband photometry of the interstellar comet 2I/Borisov (C/2019 Q4). The observations were carried out in the two months before its perihelion passage. The UBVri photometric data obtained for comet 2I were converted to its r

For two classical Cepheids, CEa Cas and CEb Cas, members of the open cluster NGC 7790, we have constructed $$O-C$$ diagrams spanning a time interval of 125 years. The $$O-C$$ diagrams have the shape of parabolas, which has allowed us for the first ti

Results of the first multicolor photometric observations of the unusual dwarf nova V2466 Cygni during its 2003 and 2019 superoutbursts are presented. The total amplitude of the 2019 superoutburst in the $$R_{c}$$ band is 7.4 magnitudes. A single rebr

H 3-75 is a medium-excitation planetary nebula with a binary central star consisting of a hot subdwarf with $$T_{\textrm{hot}}\sim 10^{5}$$ K and a cool giant. We present the results of our photometric and spectroscopic observations obtained in 2020
