Perihelion precession for modified Newtonian gravity
We calculate the perihelion precession δ for nearly circular orbits in a central potential V (r). Differently from other approaches to this problem, we do not assume that the potential is close to the Newtonian one. The main idea in the deduction is to apply the underlying symmetries of the system to show that δ must be a function of r · V (r)/V (r), and to use the transformation behaviour of δ...
متن کاملLight bending and perihelion precession: A unified approach
The standard General Relativity results for precession of particle orbits and for bending of null rays are derived as special cases of perturbation of a quantity that is conserved in Newtonian physics, the Runge-Lenz vector. First this method is applied to give a derivation of these General Relativity effects for the case of the spherically symmetric Schwarzschild geometry. Then the lowest orde...
متن کاملMultipole Corrections to Perihelion and Node Line Precession
According to Kepler’s law, a probe particle orbiting around a central spherical mass describes a trajectory with the shape of an ellipse. When particles are not pointlike or they are not even spherical, distortions appear and orbits are no longer closed, according to Bertrand’s theorem. In such cases we talk of precession. There are many phenomena comprised in this word, the precession of the r...
متن کاملGravitational Thomas Precession and the Perihelion Advance of Mercury
Gravitational Thomas Precession ( GTP ) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The GTP gives a negative contribution of 7 · 163 arcsec/century for the anomalous perihelion advance of Mercury’s orbit.This effect seems to be of some concern for the General Relativity. PACS: 04.80Cc ; 96.30Dz
متن کاملPerihelion Precession in spherically symmetric Kaluza-Klein Theories
We consider the perihelion precession and bending of light in a class of KaluzaKlein models and show that the “electric redshift” model, proposed in Zhang (2006) to explain the redshift of Quasars, does not agree with observations. As Zhang’s model only considers the Jordan frame, we also compute the perihelion precession as seen in the Einstein frame and show that, to lowest order, the perihel...
