Wedging spacetime principal null directions
D. Bini, A. Geralico, R. T. Jantzen
Taking wedge products of the distinct principal null directions associated with the eigen-bivectors of the Weyl tensor associated with the Petrov classification, when linearly…
Petrov type I spacetime curvature: principal null vector spanning dimension
Donato Bini, Andrea Geralico, Robert T. Jantzen
The class of Petrov type I curvature tensors is further divided into those for which the span of the set of distinct principal null directions has dimension four (maximally spannin…
Gödel spacetime, planar geodesics and the Möbius map
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
Timelike geodesics on a hyperplane orthogonal to the symmetry axis of the Gödel spacetime appear to be elliptic-like if standard coordinates naturally adapted to the cylindrical sy…
Godel spacetime: elliptic-like geodesics and gyroscope precession
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
We study elliptic-like geodesic motion on hyperplanes orthogonal to the cylindrical symmetry axes of the Godel spacetime by using an eccentricity-semi-latus rectum parametrization…
Black hole geodesic parallel transport and the Marck recipe for isolating cumulative precession effects
Donato Bini, Andrea Geralico, Robert T. Jantzen
The Wigner rotations arising from the combination of boosts along two different directions are rederived from a relative boost point of view and applied to gyroscope spin precessio…
Position determination and strong field parallax effects for photon emitters in the Schwarzschild spacetime
Donato Bini, Andrea Geralico, Robert T. Jantzen
Position determination of photon emitters and associated strong field parallax effects are investigated using relativistic optics when the photon orbits are confined to the equator…
