| Abstract | We propose a 60 ks observation to probe the nature of the youngest HMXBdiscovered with its associated SNR (MCSNR J0513-6724). The existing XMM-Newtonobservation shows tentative pulsations from the HMXB which needs confirmation.The estimated age is <6 kyr. A very young system can switch on as an accretingpulsar only when the spin period has reached a critical value. This implies anupper limit of B<5 10e11 G. A young NS observed with a low B strength wouldstrongly imply magnetic field burial by an episode of post-supernovahyper-critical accretion, which if confirmed will be the first ever to beobserved in a HMXB. A dedicated observation of MCSNR J0513-6724 will provide theunique opportunity to probe the physics of accretion onto NS at early evolutionary stages. |

| 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. |
