SRGe2149+6736 -- the new candidate to AM~Her type variables discovered by eROSITA telescope on "Spectrum--Roentgen--Gamma" orbital observatory
I. F. Bikmaev, A. I. Kolbin, V. V. Shimansky +18
We present the results of the optical identification, classification, as well as analysis of photometric and spectral observations of the X-ray transient SRGe2149+6736 detected by…
New Luminous Blue Variable Candidates in NGC 4736
Y. Solovyeva, A. Vinokurov, S. Fabrika +8
We have found three new LBV candidates in the star-forming galaxy NGC 4736. They show typical well-known LBV spectra, broad and strong hydrogen lines, He I lines, many Fe II lines,…
Spectroscopic study of the optical counterpart to the Fast X-ray Transient IGR J17544-2619 based on observations at the 1.5-m RTT-150 telescope
I. F. Bikmaev, E. A. Nikolaeva, V. V. Shimansky +7
We present the results of our long-term photometric and spectroscopic observations at the Russian-Turkish RTT-150 telescope for the optical counterpart to one of the best-known sou…
Modeling of the spectral energy distribution of the cataclysmic variable TT Ari and evaluation of the system parameters
K. V. Belyakov, V. F. Suleimanov, E. A. Nikolaeva +1
The spectral energy distribution (SED) of the TT Ari system, which is well known from published IUE and optical photometric observations, was modeled by a steady-state accretion α-…
