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…

Monitoring of DDO68 'Northern Ring' SF regions during years 2016-2023

S. A. Pustilnik, Y. A. Perepelitsyna, A. S. Vinokurov +6

DDO68 is a star-forming (SF) dwarf galaxy residing in a nearby void. Its gas metallicity is among the lowest known in the local Universe, with parameter 12+log(O/H) in the range of…

Spectroscopic and photometric study of the new eclipsing polar Gaia23cer

A. I. Kolbin, E. P. Pavlenko, V. Yu. Kochkina +11

We present the results of the optical study of the new eclipsing polar Gaia23cer. We analyzed the brightness variability of the polar in high ($\langle r \rangle \approx 16.5\mathr…

SDSS J085414.02+390537.3 -- a new asynchronous polar

A. I. Kolbin, M. V. Suslikov, V. Yu. Kochkina +3

The asynchrony of the polar SDSS~J085414.02+390537.3 was revealed using the data of ZTF photometric survey. The light curves show a beat period ~days. Duri…

Long-term optical spectral monitoring of a changing-look active galactic nucleus NGC 3516 -- II. Broad-line profile variability

Luka C. Popović, Dragana Ilić, Alexander Burenkov +10

We analyze the broad H line profile variability of the "changing look" active galactic nucleus (CL-AGN) NGC 3516 over a long period of 25 years. The observed change in the broad…

Optical study of the polar BM CrB in low accretion state

A. I. Kolbin, N. V. Borisov, A. N. Burenkov +3

This paper presents a spectral and photometric study of the poorly studied polar BM CrB. Three states of the polar brightness and signs of transition from one-pole to two-pole accr…
