چکیده
Mass currents in astrophysics generate gravitomagnetic fields of enormous complexity. Gravitomagnetic helicity, direct analogy with magnetic is a measure entwining the field lines. We discuss helicity within gravitoelectromagnetic (GEM) framework linearized general relativity. Furthermore, we employ spacetime curvature approach to GEM order determine for static observers Kerr spacetime.

Gravitomagnetic Effects
RESUME The paper summarizes the most important effects in Einsteinian gravitomagnetic fields related to propagating light rays, moving clocks and atoms, orbiting objects, and precessing spins. Emphasis is put onto the gravitational interaction of spinning objects. The gravitomagnetic field lines of a rotating or spinning object are given in analytic form.
متن کاملGravitomagnetic Effects
This paper contains a review of the theory and practice of gravitomag-netism, with particular attention to the different and numerous proposals which have been put forward to experimentally or observationally verify its effects. The basics of the gravitoelectromagnetic form of the Ein-stein equations is expounded. Then the Lense-Thirring and clock effects are described, reviewing the essentials...
متن کاملOn the Gravitomagnetic Time Delay
We study the gravitational time delay in ray propagation due to rotating masses in the linear approximation of general relativity. Simple expressions are given for the gravitomagnetic time delay that occurs when rays of radiation cross a slowly rotating shell, equation (14), and propagate in the field of a distant rotating source, equation (16). Moreover, we calculate the local gravitational ti...
متن کاملEvidence of the gravitomagnetic field of Mars
According to general relativity, the gravitomagnetic Lense-Thirring force of Mars would secularly shift the orbital plane of the Mars Global Surveyor (MGS) spacecraft by an amount of 1.5 m, on average, in the cross-track direction over 5 years. The determined cross-track postfit residuals of MGS, built up by neglecting just the gravitomagnetic force in the dynamical force models and without fit...
متن کاملGravitomagnetic moments of the fundamental fields
The quadratic form of the Dirac equation in a Riemann spacetime yields a gravitational gyromagnetic ratio κS = 2 for the interaction of a Dirac spinor with curvature. A gravitational gyromagnetic ratio κS = 1 is also found for the interaction of a vector field with curvature. It is shown that the Dirac equation in a curved background can be obtained as the square–root of the corresponding vecto...
