Possible Electromagnetic Phenomena during the Coalescence of Neutron Star-Black Hole Binary Systems
K. A. Postnov, A. G. Kuranov, I. V. Simkin
Possible models for the generation of electromagnetic (EM) radiation during the coalescence of neutron star-black hole binaries are considered. The mass of the remnant disk around…
Spins of black holes in coalescing compact binaries
K. Postnov, A. Kuranov, N. Mitichkin
Modern astrophysical methods of determination of spins of rotating stellar-mass black hole in close binaries and of supermassive black holes in active galactic nuclei are briefly d…
Wind-accreting Symbiotic X-ray Binaries
Lev Yungelson, Alexandre Kuranov, Konstantin Postnov
We present a new model of the population of symbiotic X-ray binaries (SyXBs) that takes into account non-stationary character of quasi-spherical sub-sonic accretion of the red gian…
X-ray binaries with neutron stars at different accretion stages
Konstantin Postnov, Aleksandre Kuranov, Lev Yungelson
Different accretion regimes onto magnetized NSs in HMXBs are considered: wind-fed supersonic (Bondi) regime at high accretion rates ~[g s] , s…
Virtually free finite-normal-subgroup-free groups are strongly verbally closed
Anton A. Klyachko, Andrey M. Mazhuga, Veronika Yu. Miroshnichenko
Any virtually free group containing no non-trivial finite normal subgroup (e.g., the infinite dihedral group) is a retract of any finitely generated group containing as a v…
Nonparametric estimation of multivariate distribution function for truncated and censored lifetime data
Valery Baskakov, Anna Bartunova
A number of models for generating statistical data in various fields of insurance, including life insurance, pensions, and general insurance have been considered. It is shown that…
