Radiation from collapsing relativistic stars. II. Linearized evenparity radiation.
Abstract
Evenparity electromagnetic and gravitational linear perturbations of OppenheimerSnyder collapse are studied. The evenparity electromagnetic problem is shown to be identical to the analogous oddparity electromagnetic problem. For the gravitational case, the mathematical appearance of the evenparity problem is markedly different from that for oddparity. Numerical results are presented, however, which show that exterior radiation fields develop quite similarly in the two problems and that previous conclusions (dominance of quasinormal ringing, powerlaw tails at late times) for oddparity radiation apply equally well to the evenparity case.
