Standard accretion disk theory is formulated which is based on the local heat balance. The energy produced by a turbulent viscous heating is supposed to be emitted to the sides of the disc. Sources of turbulence in the accretion disc are connected wi

The interaction of atomic magnetic moments with non-uniform magnetic fields may be important for the diffusion in the matter near the surface of neutron and magnetic stars. Formation of the anomalous abundance of some elements in magnetic stars is co

The observational properties of Soft Gamma Repeaters and Anomalous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neutron star. The model, where the source of the energy is connected with a

Numerical simulations of the cold supersonic flows in different astrophysical problems meets with the loss of precision difficulty. For to overcome the difficulty it was suggested earlier to use conservation entropy equation instead of energy conserv

We consider the Kepler two-body problem in the presence of a cosmological constant [Formula: see text]. Several dimensionless parameters characterizing the possible orbit typologies are used to identify open and closed trajectories. The qualitative p

The spectrum of cyclotron radiation is calculated for anisotropically distributed relativistic electrons with a nonrelativistic velocity scattering across the magnetic field. It is shown that if such electrons are responsible for a formation of the "

We consider stationary out flowing stellar envelopes accelerated by a radiation flux pressure. A method is developed describing a spherically symmetric flow in radiational hydrodynamics in regions with arbitrary optical depth (τ ). The solution of t
