- W1514572731 abstract "The X-ray source RX J0822-4300 is thought to be the compact stellar remnant formed in a core collapse supernova about 3700 years ago. However, the emission properties observed from this source are completely different from what are observed in other young neutron stars. RX J0822-4300 was therefore the target of several deep X-ray observations with the X-ray observatories XMM-Newton and Chandra. In this work, we present for the first time the results of a data analysis which makes use of all of these data. With the subarcsecond spatial resolution of Chandra, we confirm the point source nature of RX J0822-4300. No plerionic X-ray emission powered by RX J0822-4300 was detected. Spectral analysis suggests that the X-ray emission from RX J0822-4300 is of thermal origin and is emitted from areas with an anisotropic heat distribution. A search for X-ray pulsations from RX J0822-4300 revealed an interesting periodicity candidate which, if confirmed, does not support a scenario of steady spin-down." @default.
