    The Death of Compact Binary Stars (1997)

    Notes: Abstract Merging rates for compact binaries (double neutron stars or black holes) are calculated based on modern concepts of binary star evolution. It is found that the first laser interferometers, with rms sensitivities of 10-21 at a frequency of 100 Hz, can detect 10-700 black holes and only ∼1 neutron star coalescences in a 1-year integration time. The implications of evolutionary effects for the cosmological origin of gamma ray bursts are also discussed.

    A model of two-stream non-radial accretion for binary X-ray pulsars (1982)
    Springer
    Astrophysics and space science 82 (1982), S. 343-361 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The general case of non-radial accretion is assumed to occur in real binary systems containing X-ray pulsars. The structure and the stability of the magnetosphere, the interaction between the magnetosphere and accreted matter, as well as evolution of neutron star in close binary system are examined within the framework of the two-stream model of nonradial accretion onto a magnetized neutron star. Observable parameters of X-ray pulsars are explained in terms of the model considered.

    Some properties of white-dwarf collapse in low-mass binaries (1983)
    Springer
    Astrophysics and space science 97 (1983), S. 121-126 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Conditions for collapse of an accreting white dwarf in a low-mass close binary are analysed. It is shown that if the magnetic strength on the surface of a white dwarf is less than 105–106 G, a rotation barrier appears which prevents the direct formation of a neutron star. As a result, a time-scale for the collapse is defined by a specific time of momentum dissipation rather than by free-fall time-scale. It is noted that a tidal deformation of a white dwarf, intensified in a process of collapse, renders collapse in a low-mass close binary sharply anisotropic. Consequently fast moving radiopulsars can arise with velocities of some thousands km s−1.

    Ejection from pulsars in binary systems (1984)

    ISSN: 1572-946X

    Topics: Physics
    Notes: Abstract Interaction of an ejecting pulsar in a binary with a matter surrounding it is considered. Around the pulsar a cavern is formed, and its shape calculated. Non-stationary regime of ‘floating’ caverns filled with binary radioemission is discussed. This regime can lead to a special radio-burster. It is noticed that in binaries with rather large separation between components a pulsed radioemission from a pulsar can be observable. In this case, the pulsar will be a fine probe for exploration of physical characteristics of a stellar wind from a normal expansion.

    Notes: Abstract A convenient diagram for an analysis of astrophysical appearances and evolution of magnetized neutron stars has been proposed. The diagram gives a general approach to such different objects as radiopulsars, X-ray pulsars, gamma-ray bursters, the SS 433 source, and others.

    Tests for coalescing binary neutron stars as cosmological origin of gamma-ray bursts (1995)

    Notes: Abstract Theoretical logN-logS distributions and (V/V max) tests of gamma-ray bursts in the model of coalescence of neutron star (NS+NS) and/or NS+black hole (NS+BH) binaries are calculated for a flat Universe (Ω=1) with different values of the cosmological constant Λ and under various assumptions about the star formation history. The observed logN-logS distribution and value of (V/V max)=0.33 for 411 bursts with knownC max/C lim from the 2d BATSE catalogue are best fitted with a model for which ΩΛ = 0.2 and primary star formation occurs at redshiftsz≃5–6.

    Cosmological rates of coalescing neutron stars and GRB (1995)
    Springer
    Astrophysics and space science 231 (1995), S. 389-392 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Assuming that gamma-ray bursts (GRB) originate from binary neutron star (NS) or black holes (BH) merging in distant galaxies, theoretical logN-logS distributions for gamma-ray bursts (GRB) are calculated using the compact binaries coalescence rates computed for model galaxies with different star formation histories. A flat cosmological model (Ω = 1) with different values of the cosmological constant Λ is used. The calculated source evolution predicts a 5–10 times increase of the source statistics at count rates 3–10 times lower than the existing BATSE sensitivity limit. The most important parameter in fitting the 2nd BATSE catalogue is the initial redshift of star formation, which is found to bez * = 2 — 5 depending on a poorly determined average spectral index of GRB.

    Dynamical friction and formation of structures: Some cosmological and cosmogonical aspects (1986)
    Springer
    Astrophysics and space science 123 (1986), S. 393-402 
    Details
    ISSN: 1572-946X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The influence of dynamical friction on peculiar velocities in a two-component medium is considered. One of the components is assumed to consist of heavy particles with small gravitational interactions and the other is assumed uniform and its particles of much less weight. Here the solutions for the stationary as well as for the cosmologically expanding medium are obtained. These solutions illustrate the possibility for clusters of galaxies to have super-low velocities. It is emphasized that the presence of two components leads to the formation of individual strings and general string structure in one of the component. A string-like structure of the Universe becomes inevitable in the case when an initial perturbations spectrum has a specific scale, and falls down abruptly for larger and smaller distances. Such a picture of the formation of large-scale structure of the Universe is similar to the formation of particle tracks in the Wilson chamber, where tracks are the observational clusters of galaxies, and ‘particles’ are invisible perturbations in the second (neutrino?) component.
