Investigation of the Nature of the B[e] Star CI Cam in the Optical Range
E. A. Barsukova, A. N. Burenkov, V. P. Goranskij +10
We report the results of 24 years of photometric and spectroscopic monitoring of CI Cam since its outburst in 1998. In the early years of our research, we identified a system compo…
Evolution of the optical emission lines and the X-ray emission during the super-active stage of T CrB
K. A. Stoyanov, G. J. M. Luna, R. K. Zamanov +6
T CrB is a symbiotic star that experiences nova outbursts every 80~yr. The next, long-anticipated nova outburst should occur during the 2024-2026 period. Here, we present re…
Size of the accretion disc in the recurrent nova T CrB
R. K. Zamanov, K. A. Stoyanov, V. Marchev +7
We present high resolution (0.06 A/px) spectroscopic observations of the recurrent nova T Coronae Borealis obtained during the last 1.5 years (September 2022 -- January 2024), with…
Luminosity class of the symbiotic stars 4U1954+319 and ZZ CMi
R. Zamanov, K. A. Stoyanov, G. Latev +8
We performed optical photometry and spectral observations of the symbiotic stars 4U1954+319 and ZZ CMi. For 4U1954+319 using high-resolution spectra we measure the equivalent width…
