Recurrent Symbiotic Nova T Coronae Borealis Before Outburst
N. A. Maslennikova, A. M. Tatarnikov, A. A. Tatarnikova +5
The results of photometric and spectral observations of T CrB obtained in a wide range of wavelengths in 2011-2023 are presented. We use the near-IR light curves to determine a new…
Long-term multiwavelength monitoring and reverberation mapping of NGC 2617 during a changing-look event
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +32
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC~2617 carried out from 2016 until 2022 and covering the wavelength range fr…
The Post-AGB Star IRAS 07253-2001: Pulsations, Long-Term Brightness Variability and Spectral Peculiarities
N. P. Ikonnikova, M. A. Burlak, A. V. Dodin +5
The observations and comprehensive study of intermediate initial mass stars at the late stages of evolution, and after the asymptotic giant branch (AGB) in particular, are of cruci…
Spectroscopic Searches for Evolutionary Orbital Period Changes in WR+OB Binaries: The case of CQ Cep and CX Cep
I. Shaposhnikov, A. Cherepashchuk, A. Dodin +1
We present the results of spectroscopic observations of two eclipsing WR+OB-type systems - CQ Cep and CX Cep, performed in 2020-2023 with a low-resolution slit spectrograph TDS ($λ…
Evolutionary Increase of the orbital Separation and Change of the Roche Lobe Size in SS433
Anatol Cherepashchuk, Alexander Belinski, Alexander Dodin +1
We present results of long-term photometric monitoring of SS433 which proves a secular evolutionary increase of the orbital period of SS433 at a rate of $(1.14\pm 0.25)\times 10^{-…
