Discovery of The New WZ Sge Star, SDSS J080434.20+510349.2
E. Pavlenko, S. Yu. Shugarov, N. A. Katysheva +13
We present the results of photometric observations of SDSS J080434.20+510349.2 in its low state and during an outburst and spectroscopy during the outburst. We found such peculiari…
Spectropolarimetry and Infrared Photometry of Magnetic White Dwarfs: Vacuum Polarization Effect or Magnetic CIA?
Yu. N. Gnedin, N. V. Borisov, V. M. Larionov +3
We present brief review of two probable physical mechanisms that can explain the results of photometric and spectropolarimetric observations of magnetic white dwarfs: vacuum polari…
Magnetic and Electric Fields around the Black Hole in Cyg X-1
Yu. N. Gnedin, N. V. Borisov, T. M. Natsvlishvili +2
Analysis of polarimetric observations of X-ray binary Cyg X-1/HDE 226868 including the data obtained by BTA-6m allows to estimate the magnetic field magnitude near the inner radius…
Spectroscopy and Doppler tomography of BZ Ursae Majoris in quiescence
V. V. Neustroev, A. Medvedev, S. Turbin +1
We present the first results of time-resolved spectroscopic observations of little-studied dwarf nova BZ Ursae Majoris in quiescence.
Modelling emission line profiles of a non-uniform accretion disk
N. V. Borisov, V. V. Neustroev
Techniques of calculation of emission line profiles formed in a non--uniform accretion disk is presented. Change of the profile shape as a function of phase turn of the disk with a…
