Post-AGB candidate IRAS 02143+5852: Cepheid-like variability, three-layer circumstellar dust envelope and spectral features
N. P. Ikonnikova, M. A. Burlak, A. V. Dodin +8
We present the results of multicolour photometry, spectroscopic analysis and spectral energy distribution (SED) modelling for the post-AGB candidat…
Analysis of the interstellar matter at the periphery of the supershell surrounding the CYG OB1 association in 2.12 micron molecular hydrogen line
D. S. Wiebe, T. G. Sitnik, A. S. Rastorguev +7
We present observations of the vdB 130 cluster vicinity in a narrow-band filter centered at a m molecular hydrogen line performed at the Caucasus Mountain Observatory of t…
Multi-Wavelength Monitoring and Reverberation Mapping of a Changing Look Event in the Seyfert Galaxy NGC 3516
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +26
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC 3516 carried out in 2018 to 2020 covering the wavelength range from the X-…
Discovery of a hot ultramassive rapidly rotating DBA White Dwarf
M. S. Pshirkov, A. V. Dodin, A. A. Belinski +6
We report the discovery of a nearby massive white dwarf with He-H atmosphere. The white dwarf is located at a distance of pc. Its radius, mass, effective temperature,…
Differential Speckle Polarimetry of Betelgeuse in 2019-2020: the rise is different from the fall
Boris Safonov, Alexandr Dodin, Marina Burlak +6
Recently published episodic spectral (Levesque and Massey, 2020) and high angular resolution (Montarges et al, 2020) observations of Betelgeuse suggest that the deep minimum of 201…
