摘 要: | A series of newly published papers are focusing on the formation of the absorption features discovered by Chandra and XMM-Newton from the young radio quiet x-ray pulsar 1E 1207.4-5209.We try to interpret it as cyclotron absorption lines since this possibility could not be ruled out .With new development and application of a hybrid model.i.e.,the magnetic dipole spin-down model combined with the neutrino cyclotron radiation spin-down model.we can easily avoid the contradiction between the normal rotation energy loss rate and the relatively lower magnetic field,and then we obtain the possible initial spin period(-0.420s) .We suppose that the progenitor of 1E 1207.4-5209 may be a white dwarf.
