چکیده

Following the procedure of Hoenselaers and Perjés we present a new corrected and dimensionally consistent set of multipole gravitational and electromagnetic moments for stationary axisymmetric spacetimes. Then, we use them to compute the multipole moments, both gravitational and electromagnetic, of a KerrNewman black hole.

Explicit multipole moments of stationary axisymmetric spacetimes

In this article we study multipole moments of axisymmetric stationary asymptotically flat spacetimes. We show how the tensorial recursion of Geroch and Hansen can be reduced to a recursion of scalar functions. We also demonstrate how a careful choice of conformal factor collects all moments into one complex valued function on R, where the moments appear as the derivatives at 0. As an applicatio...

Multipole moments of axisymmetric spacetimes

In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion. This is a generalisation of a method developed by Herberthson for the static case. Using Herberthson’s method we also devel...

Fully electrified Neugebauer spacetimes.

Generalizing a method presented in an earlier paper, we express the complex potentials E and Φ of all stationary axisymmetric electrovac spacetimes that correspond to axis data of the form directly associated with the various multipole moments.

Measuring mass moments and electromagnetic moments of a massive, axisymmetric body, through gravitational waves

The electrovacuum around a rotating massive body with electric charge density is described by its multipole moments (mass moments, mass-current moments, electric moments, and magnetic moments). A small uncharged test particle orbiting around such a body moves on geodesics if gravitational radiation is ignored. The waves emitted by the small body carry information about the geometry of the centr...

Revising the multipole moments of numerical spacetimes and its consequences.

Identifying the relativistic multipole moments of a spacetime of an astrophysical object that has been constructed numerically is of major interest, both because the multipole moments are intimately related to the internal structure of the object, and because the construction of a suitable analytic metric that mimics a numerical metric should be based on the multipole moments of the latter one ...
