Abrupt Changes in the Multipole Moments of a Gravitating Body
C. Barrabès, G. F. Bressange, P. A. Hogan
An example is described in which an asymptotically flat static vacuum Weyl space-time experiences a sudden change across a null hypersurface in the multipole moments of its isolate…
Colliding Plane Waves in Einstein-Maxwell Theory
C. Barrabès, G. F Bressange, P. A. Hogan
Recently a simple solution of the vacuum Einstein-Maxwell field equations was given describing a plane electromagnetic shock wave sharing its wave front with a plane gravitational…
Implications of Spontaneous Glitches in the Mass and Angular Momentum in Kerr Space-Time
C. Barrabès, G. F. Bressange, P. A. Hogan
The outward-pointing principal null direction of the Schwarzschild Riemann tensor is null hypersurface-forming. If the Schwarzschild mass spontaneously jumps across one such hypers…
Singular Hypersurfaces in Scalar-Tensor Theories of Gravity
C. Barrabes, G. F. Bressange
We study singular hypersurfaces in tensor multi-scalar theories of gravity. We derive in a distributional and then in an intrinsic way, the general equations of junction valid for…
Some Physical Consequences of Abrupt Changes in the Multipole Moments of a Gravitating Body
C. Barrabes, G. F. Bressange, P. A. Hogan
The Barrabès-Israel theory of light-like shells in General Relativity is used to show explicitly that in general a light-like shell is accompanied by an impulsive gravitational wav…
