Rotating incompressible perfect fluid source of the NUT metric
László Á. Gergely, Zoltán Perjés, Gyula Fodor
A global solution of the Einstein equations is given, consisting of a perfect fluid interior and a vacuum exterior. The rigidly rotating and incompressible perfect fluid is matched…
Spin effects in radiating compact binaries
László Á. Gergely, Zoltán Perjés, Mátyás Vasúth
We review and summarize our results concerning the influence of the spins of a compact binary system on the motion of the binary and on its gravitational reaction. We describe brie…
Colliding spherically symmetric null dust in equilibrium
László Á. Gergely
We present two recently obtained solutions of the Einstein equations with spherical symmetry and one additional Killing vector, describing colliding null dust streams.
A rotating incompressible perfect fluid space-time
Zoltán Perjés, Gyula Fodor, László Á. Gergely +1
A rigidly rotating incompressible perfect fluid solution of Einstein's gravitational equations is discussed. The Petrov type is D, and the metric admits a four-parameter isometry g…
Radiation Backreaction in Spinning Binaries
László Á. Gergely, Zoltán Perjés, Mátyás Vasúth
The evolution under radiation backreaction of a binary system consisting of a black hole and a companion is studied in the limiting case when the spin of the companion is negligibl…
