Dragging of inertial frames inside the rotating neutron stars
Abstract
We derive the exact framedragging rate inside rotating neutron stars. This formula is applied to show that the framedragging rate monotonically decreases from the center to the surface of the neutron star along the pole. In the case of the framedragging rate along the equatorial distance, it decreases initially away from the center, becomes negligibly small well before the surface of the neutron star, rises again, and finally approaches to a small value at the surface. The appearance of a local maximum and minimum in this case is the result of the dependence of framedragging frequency on the distance and angle. Moving from the equator to the pole, it is observed that this local maximum and minimum in the framedragging rate along the equator disappear after crossing a critical angle. It is also noted that the positions of the local maximum and minimum of the framedragging rate along the equator depend on the rotation frequency and central energy density of a particular pulsar.

We determine here the offdiagonal metric components (the LenseThirring terms) resulting from the rotation of an oblate ellipsoid of revolution stratified into similar concentric elliptic layers of equal density. To find the unique function H involved in these offdiagonal components, we use a set of characteristic properties which may be compared with the wellknown characteristic properties of the Newtonian potentials. We get H in terms of usual functions when the spinning ellipsoid is homogeneous. Applying this result to the Galaxy, we show that the dragging of inertial frames induced by the galactic rotation is too small to be presently detected.more »

Satellite test for dragging of inertial frames
It is shown that it is possible by using the lack of synchronization of clocks by light signal synchronization in elliptical orbits to test for the dragging of inertial frames in Einstein's theory of general relativity. Possible experiments are discussed. 
Gravitational light deflection and the dragging of inertial frames
The gravitational field generated by currents of matter within a body influences the deflection of light by the body. We show that in metric theories of gravity the Einstein equivalence principle implies a deeper connection than had been realized between this deflection and the LenseThirring dragging of inertial frames. 
Geodetic precession or dragging of inertial frames
In metric theories of gravity the principle of general covariance allows one to describe phenomena by means of any convenient choice of coordinate system. In this paper it is shown that in an appropriately chosen coordinate system, geodetic precession of a gyroscope orbiting a spherically symmetric, spinning mass can be recast as a LenseThirring framedragging effect without invoking spatial curvature. The origin of this reference frame moves around the source but the frame axes point in fixed directions. The drag can be interpreted to arise from the orbital angular momentum of the source around the origin of the reference frame.more » 
Clock transport synchronization and the dragging of inertial frames for elliptical orbits
It is shown that it is possible to test for the dragging of inertial frames in Einstein's theory of general relativity by using the discrepancy between clocks synchronized by clock transport in elliptical orbits. Possible experiments are discussed.
