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

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
