Celestial mechanics in Kerr spacetime [PDF]

, 2002
The dynamical parameters conventionally used to specify the orbit of a test particle in Kerr spacetime are the energy $E$, the axial component of the angular momentum, $L_{z}$, and Carter's constant $Q$.

Hyperbolic normal forms and invariant manifolds: Astronomical applications [PDF]

Serbian Astronomical Journal, 2012
In recent years, the study of the dynamics induced by the invariant manifolds of unstable periodic orbits in nonlinear Hamiltonian dynamical systems has led to a number of applications in celestial mechanics and dynamical astronomy.

Relativistic Celestial Mechanics with PPN Parameters [PDF]

, 1999
Starting from the global parametrized post-Newtonian (PPN) reference system with two PPN parameters $\gamma$ and $\beta$ we consider a space-bounded subsystem of matter and construct a local reference system for that subsystem in which the influence of ...

Satellite orbit under influence of a drag - analytical approach [PDF]

Serbian Astronomical Journal, 2017
The report studies some changes in orbital elements of the artificial satellites of Earth under influence of atmospheric drag. In order to develop possibilities of applying the results in many future cases, an analytical interpretation of the ...

Applications of KS - variables in celestial mechanics

Bibechana, 2010
This paper deals with the transformation of KS-Variables and canonically conjugate variables from sideral (inertial) to synodic (rotating) form and their applications in "the circular restricted problem of three bodies in three-dimensional coordinate ...

Daemons and DAMA: Their Celestial-Mechanics Interrelations [PDF]

, 2007
The assumption of the capture by the Solar System of the electrically charged Planckian DM objects (daemons) from the galactic disk is confirmed not only by the St.Petersburg (SPb) experiments detecting particles with ...

Celestial mechanics of elastic bodies [PDF]

, 2006
We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their center of mass or strictly static configurations.Comment: 16 pages, 2 figures,

DYNAMICAL EVOLUTION NEAR-PARABOLIC COMETS TO HALLEY-TYPE ORBITS

Odessa Astronomical Publications, 2017
The capture of comet from the near parabolic flux of the Oort cloud to Halley-type orbits (P < 200 yr, perihelion distanses q < 1,5 AU, and Tisserand parametr T < 2) is investigated Two types of capture into Halley-type orbits are found.

Symmetries in central-force problems [PDF]

Serbian Astronomical Journal, 2003
The two-body problem in central fields (reducible to a central-force problem) models a lot of concrete astronomical situations. The corresponding vector fields (in Cartesian and polar coordinates, extended via collision-blow-up and infinity-blow-up ...
