Absorption Phenomena and a Probable Blast Wave in the 13 July 2004 Eruptive Event
V. V. Grechnev, A. M. Uralov, V. A. Slemzin +3
We present a case study of the 13 July 2004 solar event, in which disturbances caused by eruption of a filament from an active region embraced a quarter of the visible solar surfac…
Polarization of cosmic microwave background scattered by moving flat protoobjects
N. N. Shakhvorostova, S. I. Grachev, V. K. Dubrovich
The work is devoted to the investigations of possible observational manifestations of protoobjects related to "dark ages" epoch (10 < z < 1000), before formation of self-luminous g…
Energy exchange inside SN ejecta and light curves of SNe Ia
E. I. Sorokina, S. I. Blinnikov
A treatment of line opacity in expanding medium is most crucial for the light curve (LC) modeling of Type Ia supernovae (SNe Ia). Spectral lines are the main source of opacity insi…
Reflection and noise in Cygnus X-1
M. Gilfanov, E. Churazov, M. Revnivtsev
We analyzed RXTE/PCA observations of Cyg X-1 from 1996-1998. We found a tight correlation between the characteristic noise frequencies (e.g. the break frequency nu_br) and the spec…
Discovery of the secondary star of the HgMn binary kappa Cancri
T. Ryabchikova, O. Kotchoukhov, G. Galazutdinov +2
A careful investigation of a CCD spectrum of the SB1 system kappa Cnc in the spectral region 3800 A - 8000 A resulted in the discovery of the lines of the secondary star. We then a…
