Stellar Evolution and the Cosmologial Supernovae Rates
We present the results of the population synthesis of the population ofthe supernovae progenitors. Both single and double degenerate progenitorsof SN Ia are considered. We compute the cosmic rate histories for...

On the Problem of the Super Reason in Astrophysics
The Giant Silence of the Universe or the absence of "Space Miracles" is in obvious contradiction with the rapid evolution of our civilization. The most striking fact is that both these phenomena, if taken sepa...

The Death of Compact Binary Stars
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 sensitiviti...

Cosmological rates of coalescing neutron stars and GRB
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 th...

The joint evolution of normal and compact magnetized stars in close binaries: Analytical description and statistical simulation
The joint evolution of normal and compact stars in binaries of low and moderate masses (≤10M ⊙) is considered. The classification and analytical description are given for such evolution. The Monte-Carlo simulatio...

The ecology of rotators
A generalized physical object, a gravimagnetic rotator (or simply, rotator), is considered. It is specified by the three characteristics: a mass, a magnetic field, and an angular momentum. A rotator interacts ...

Dynamical friction and formation of structures: Some cosmological and cosmogonical aspects
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 ...

‘Nomadic’ nuclei of galaxies
In this paper we discuss observational and theoretical arguments in favour of hypothesis on ‘nomad life’ of active nuclei inside and outside galaxies as well as its consequences. It may be the anisotropic coll...

Accretion spin-up of low-magnetic neutron stars
The present paper is concerned with the spin-up of low-magnetic neutron stars by the accretion of matter onto the star. Calculations have been made for the evolution of the rotation of a neutron star and appli...

Ejection from pulsars in binary systems
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...

Some properties of white-dwarf collapse in low-mass binaries
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 ap...

The universal diagram for magnetized neutron stars in the galaxy
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-...

On the origin of gamma-ray bursts
A model for gamma-ray bursters which naturally explains the main observational features of GRB is proposed. The GRB turned out to be linked by evolution with a well-known type of astrophysical object.

A model of two-stream non-radial accretion for binary X-ray pulsars
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...
