Description PSR B0943+10 is the best studied mode-switching radio pulsar. Its radio emission alternates between a highly organised state with regular drifting subpulses (B mode) and a chaotic emission pattern (Q mode). XMM-Newton observations showed remarkable X-ray variability correlated with the radio mode: during the fainter radio state the X-ray flux is more than twice larger than during the B-mode and X-ray pulsations are detected. Due to the limited spectral information it is not possible to discriminate between interpretations with very different physical implications for possible global changes in the magnetosphere. We propose a large program with coordinated radio observations on this unique target to gain insight into the pulsar emission mechanism expoiting the new diagnostic of X-ray variability.

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.
