Timing the Newly Discovered Pulsar at the Center of Supernova Remnant Kes 79
收藏资源简介：
We have discovered 105ms Xray pulsations from the compact central object (CCO)in the supernova remnant Kes 79, one of six enigmatic Xray emitters whosenature is a great mystery. We propose to follow the allimportant spindownevolution in order to quantify the energetics of the pulsar and test whether itis powered by rotation, accretion, or a more exotic process. We will compare thetiming properties of this pulsar with 1E 1207.45209 in PKS 120951/52, the onlyother confirmed CCO pulsar, whose strange spindown irregularity suggests thatit might not be an isolated NS. The relationship between ordinary pulsars, CCOs,and anomalous Xray pulsars, may be greatly illuminated by timing measurementsof this new pulsar. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
