The rotation curve and mass-distribution in highly flattened galaxies
N. R. Sibgatullin, A. A. Garcia, V. S. Manko
A new method is developed which permits the reconstruction of the surface-density distribution in the galactic disk of finite radius from an arbitrary smooth distribution of the an…

Determining the surface density distribution in massive galactic disks with a central black hole
N. R. Sibgatullin, A. Garcia, V. S. Manko
An efficient method is developed which allows the calculation of distributions of the surface density in the equilibrium disk configurations with an isolated point mass at the cent…

The Disc Accretion in Gravitational Field of a Rapidly Rotating Neutron Star with a Rotationally Induced Quadrupole Mass Distribution
N. R. Sibgatullin, R. A. Sunyaev
We analyze the effect of the quadrupole component in the mass distribution of a rapidly rotating neutron star on energy release in the boundary layer on the surface of the accretin…
