LETTER Frame Dragging Anomalies for Rotating Bodies
The prototype example of frame dragging arises in the Kerr metric. A test particle with zero angular momentum released from a nonrotating frame, far from the source of the Kerr metric, accumulates nonzero angular velocity in the same angular direction as the source of the metric, as the test particle plunges toward the origin (in Boyer-Lindquist coordinates). This “dragging of inertial frames,”...
متن کاملFrame Dragging Anomalies for Rotating Bodies
Examples of axially symmetric solutions to Einstein's field equations are given that exhibit anomalous " negative frame dragging " in the sense that zero angular momentum test particles acquire angular velocities in the opposite direction of rotation from the source of the metric.
متن کاملFrame dragging and super – energy
We show that the vorticity appearing in stationary vacuum spacetimes is always related to the existence of a flow of super–energy on the plane orthogonal to the vorticity vector. This result, toghether with the previously established link between vorticity and super–energy in radiative (Bondi–Sachs) spacetimes strength further the case for this latter quantity as the cause of frame dragging.
متن کاملRelativistic precession around rotating neutron stars: Effects due to frame-dragging and stellar oblateness
General relativity predicts that a rotating body produces a frame-dragging (or LenseThirring) effect: the orbital plane of a test particle in a non-equatorial orbit precesses about the body’s symmetry axis. In this paper we compute the precession frequencies of circular orbits around rapidly rotating neutron stars for a variety of masses and equations of state. The precession frequencies comput...
متن کاملGravitomagnetism, Frame-dragging and Lunar Laser Ranging
Gravitomagnetism is a phenomenon predicted by Einstein’s theory of General Relativity, it consists in the interaction generated by a mass current in a way formally similar to magnetism generated by an electric current. A number of experiments have been proposed and carried out to accurately measure the gravitomagnetic interaction. The LAGEOS satellites observations [1], using the GRACE models, ...
