Observations of thermal components in the X-ray spectra of young pulsars provideinsights into fundamental physics of neutron star interiors and magnetospheres.A short XMM-Newton exposure of the 7 kyr old PSR J1357 6429 has revealed thermalemission from the NS surface and an elongated diffuse feature extending from thepulsar, most likely a pulsar wind nebula (PWN). Observations with Chandra HRC-Shave have provided tentative detections of a compact PWN and pulsations. Here wepropose a detailed study of the pulsar.s spectral and timing properties, anddeep imaging and spectroscopy of the PWN with XMM-Newton and Chandra.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
