The generalized Roche model
Zakir F. Seidov
Some exact analytical formulas are presented for the generalized Roche model of rotating star. The gravitational field of the central core is described by the model of two equal-ma…
Lane-Emden Equation: perturbation method
Zakir F. Seidov
The perturbation method is applied to numerical solution of the Lane-Emden Equation of arbitrary index n, and the global parameters of polytropes are found as function of polytropi…
The quasi-incompressible planet: some analytics
Zakir F. Seidov
Exact and approximate analytical formulas are derived for the internal structure and global parameters of the spherical non-rotating quasi-incompressible planet. The planet is mode…
On the angular momentum of the neutron star
Zakir F. Seidov
It is shown that the mass loss due to rotation-driven hydrodynamical instability during the catastrophic collapse of the star is small. Neutron star is formed with a large rotation…
Rotation, mass loss and pulsations of the star: an analytical model
Zakir F. Seidov
The characteristics of the star with the "prescribed" density distribution are analytically studied.
Gravitational potential energy of simple bodies: the method of negative density
Zakir F. Seidov
The method of negative density is presented which allows to obtain the analytical solutions for potential energy of new kinds of homogeneous and ihhomogeneous self-gravitating bodi…
