Description We measured spin-down of the pulsar in Puppis A, which indicates a dipole magnetic field of only 2.8E10 G, the smallest of any young neutron star. PSR J0821-4300 also has an X-ray spectral feature that is either an emission line at 0.75 keV or an absorption line at 0.46 keV. Either are consistent with electron cyclotron resonance at roughly the spin-down magnetic field strength. However, the strength and energy of the line are apparently variable in time. We propose to monitor the spectrum to test for further variability of the magnetic field. The simultaneous timing will also test for correlated torque noise that could be indicative of accretion of supernova debris, the most plausible mechanism for generating an emission line.

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.
