Symbiotic star T CrB as an extreme SU UMa type dwarf nova
Krystian Ilkiewicz, Joanna Mikolajewska, Kiril A. Stoyanov
T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poor…
BV photometric observations of the flickering of the dwarf nova RX And
R. K. Zamanov, L. Dankova, M. Moyseev +3
We report photometry of the intranight variability of the dwarf nova RX And in two bands (B and V). The observations are carried out during three nights in November-December 2022 a…
Optical spectroscopy of Be stars: peak separation of Balmer emission lines
R. K. Zamanov, K. A. Stoyanov, S. Y. Stefanov +2
The Be stars display variable optical emission lines originating in the circumstellar disc. Here we analyse high resolution spectroscopic observations of Be stars and the distance…
Mass outflow from the symbiotic binary RS Oph during its 2021 outburst
N. A. Tomov, M. T. Tomova, K. A. Stoyanov +7
RS Oph is a symbiotic recurrent nova containing a massive white dwarf with heavy mass loss during activity. In August 2021, it underwent its seventh optical eruption since the end…
