| Description | We propose a coordinated X-ray-UV-optical campaign to study the violent flaring activity recently discovered in the evaporating binary millisecond pulsar PSR J1311 3430. This -ray binary sports the shortest pulsar orbital period, the strongest pulsar-driven wind and one of the highest neutron star-companion mass ratios known. The strong and frequent flares complicate study of the quiescent light curve and affect the energy transfer from the MSP. Our campaign probes the spectral and orbital phase distribution of these flares, revealing their location, size and radiation physics. In turn this provides a key to understanding this extreme system and companion-evaporating pulsars, as a class. |

| 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. |
