A rotating incompressible perfect fluid space - time
A rigidly rotating incompressible perfect fluid solution of Einstein’s gravitational equations is given. The Petrov type is D, and the metric admits a fourparameter isometry group. The Gaussian curvature of the instantaneous constantpressure surfaces is positive and they have two ring-shaped cusps. PACS numbers: 04.20.Cv, 04.20.Jb, 04.40.Dg, 97.60.-s Submitted to: Class.

متن کاملExact Relativistic Static Charged Perfect Fluid Disks
Using the well-known “displace, cut and reflect” method used to generate disks from given solutions of Einstein field equations, we construct static charged disks made of perfect fluid based on the Reissner-Nordström solution in isotropic coordinates. We also derive a simple stability condition for charged and non charged perfect fluid disks. As expected, we find that the presence of charge inc...
متن کاملThe microcanonical ensemble of the ideal relativistic quantum gas
We derive the microcanonical partition function of the ideal relativistic quantum gas of spinless bosons in a quantum field framework as an expansion over fixed multiplicities. Our calculation generalizes well known expressions in literature in that it does not introduce any large volume approximation and it is valid at any volume. We discuss the issues concerned with the definition of the micr...
متن کاملA slowly rotating perfect fluid body in an ambient vacuum
A global model of a slowly rotating perfect fluid ball in general relativity is presented. To second order in the rotation parameter, the junction surface is an ellipsoidal cylinder. The interior is given by a limiting case of the Wahlquist solution, and the vacuum region is not asymptotically flat. The impossibility of joining an asymptotically flat vacuum region has been shown in a preceding ...
متن کاملThe ideal relativistic spinning gas: polarization and spectra
We study the physics of the ideal relativistic rotating gas at thermodynamical equilibrium and provide analytical expressions of the momentum spectra and polarization vector for the case of massive particles with spin 1/2 and 1. We show that the finite angular momentum J entails an anisotropy in momentum spectra, with particles emitted orthogonally to J having, on average, a larger momentum tha...
