Quantum and Post-Newtonian Effects in the Anomalistic Period and the Mean Motion of Celestial Bodies
Ioannis Haranas, Omiros Ragos, Ioannis Gkigkitzis +1
We study the motion of a secondary celestial body under the influence of the corrected gravitational force of a primary. We study the effect of quantum and relativistic corrections…
Kretschmann Invariant and Relations Between Spacetime Singularities, Entropy and Information
Ioannis Gkigkitzis, Ioannis Haranas, Omiros Ragos
Using a yukawa type of metric we derive the kretschmann scalar for a general static black hole of a certain mass. The scalar gives the curvature of the space time as a function of…
The Lens-Thirring effect in the anomalistic period of celestial bodies
Ioannis Haranas, Omiros Ragos, Ioannis Gkigkitzis
In the weak field and slow motion approximation, the general relativistic field equations are linearized, resembling those of the electromagnetic theory. In a way analogous to that…
Radar Signal Delay in the Dvali-Gabadadze-Porrati Gravity in the Vicinity of the Sun
Ioannis Haranas, Omiros Ragos, Ioannis Gkigkitzis
In this paper we examine the recently introduced Dvali Gabadadze Porrati gravity model. We use the space time metric in which the local gravitation source dominates the metric over…
Effects in the Anomalistic Period of Celestial Bodies due to a Logarithmic Correction to the Newtonian Gravitational Potential
Omiros Ragos, Ioannis Haranas, Ioannis Gkigkitzis
We study the motion of a secondary celestial body under the influence of the logarithmic corrected gravitational force of a primary one. This kind of correction was introduced by F…
