Description We detected spin-down of the pulsar in Puppis A, which requires a dipole magnetic field of only 2.9e10 G, the smallest of any young neutron star. This confirms the anti-magnetar scenario, but there is possibly some phase jitter in the ephemeris. We also detected an X-ray spectral feature that is either an emission line at virgul0.7 keV or an absorption line at virgul0.46 keV, which is consistent with a photospheric cyclotron resonance. However, its strength is apparently variable in time. We propose to double the time span of the ephemeris to confirm the spin-down rate and test for torque noise and any spectral variability, which could be indicative of accretion of supernova debris.

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.
