研究了Oppenheimer-Snyder坍缩的偶宇称电磁和引力线性微扰。偶宇称电磁问题被证明是相同的类似的奇宇称电磁问题。在引力的情况下，偶宇称问题的数学表现与奇宇称问题的数学表现明显不同。然而，数值结果表明，外部辐射场的发展非常相似的两个问题，以前的结论（占主导地位的准正常振铃，幂律尾晚时间）奇宇称辐射同样适用于偶宇称的情况。
Even-parity electromagnetic and gravitational linear perturbations of Oppenheimer-Snyder collapse are studied. The even-parity electromagnetic problem is shown to be identical to the analogous odd-parity electromagnetic problem. For the gravitational case, the mathematical appearance of the even-parity problem is markedly different from that for odd-parity. Numerical results are presented, however, which show that exterior radiation fields develop quite similarly in the tow problems and that previous conclusions (dominance of quasi-normal ringing, power-law tails late times) for odd-parity radiation apply equally well to the even-parity case.
