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…

A flare in the optical spotted in the changing-look Seyfert NGC 3516

D. Ilic, V. Oknyansky, L. C. Popovic +14

We present observations from the short-term intensive optical campaign (from Sep2019 to Jan2020) of the changing-look Seyfert NGC 3516. This active galactic nucleus is known to hav…

The Relative Wavelength Independence of IR Time Lags in NGC4151 During the Years 2010-2015

V. L. Oknyansky, V. I. Shenavrin, N. V. Metlova +1

We present results of a study of the correlation between the infrared (JHKL) and optical(B) fluxes of the nucleus of the Seyfert galaxy NGC 4151 for the years 2010 - 2015 using our…

Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205

A. O. Simon, A. V. Bondar, N. V. Metlova

We report about new episode of decretion disk formation in the IGR J06074+2205 system. Obtained spectral data gives us opportunity to measure peak separation in double-peaked Hα li…
