Precession of timelike bound orbits in Kerr spacetime

چکیده

Abstract Astrometric observations of S-stars provide a unique opportunity to probe the nature Sagittarius-A* (Sgr-A*). In view this, it has become important understand and behavior timelike bound trajectories particles around massive central object. It is known now that whereas Schwarzschild black hole does not allow negative precession for S-stars, naked singularity spacetimes can admit positive as well orbits. this context, we study perihelion test particle in Kerr spacetime geometry. Considering some approximations, investigate whether orbits have precession. paper, only consider low eccentric equatorial With these considerations, find spacetimes, allowed.

M ay 2 00 4 Dirac Spin Precession in Kerr Spacetime by the parallelism description

In the framework of parallelism general relativity (PGR), the Dirac particle spin precession in the rotational gravitational field is studied. In terms of the equivalent tetrad of Kerr frame, we investigate the torsion axial-vector spin coupling in PGR. In the case of the weak field and slow rotation approximation, we obtain that the torsion axialvector has the dipole-like structure, but differ...

A Fast New Public Code for Computing Photon Orbits in a Kerr Spacetime

Relativistic radiative transfer problems require the calculation of photon trajectories in curved spacetime. We present a novel technique for rapid and accurate calculation of null geodesics in the Kerr metric. The equations of motion from the Hamilton-Jacobi equation are reduced directly to Carlson’s elliptic integrals, simplifying algebraic manipulations and allowing all coordinates to be com...

Timelike Minimal Submanifolds of General Co-dimension in Minkowski Spacetime

We consider the timelike minimal surface problem in Minkowski spacetimes and show local and global existence of such surfaces having arbitrary dimension ≥ 2 and arbitrary co-dimension, provided they are initially close to a flat plane.

Autoparallel Orbits in Kerr Brans-Dicke Spacetimes

The bounded orbital motion of a massive spinless test particle in the background of a Kerr Brans-Dicke geometry is analysed in terms of worldlines that are auto-parallels of different metric compatible spacetime connections. In one case the connection is that of Levi-Civita with zero-torsion. In the second case the connection has torsion determined by the gradient of the Brans-Dicke background ...
