Description We propose to observe 10 newly discovered short period binary millisecond pulsars with XMM-Newton. These millisecond pulsar binaries show evidence for interaction with their low mass companions which sometimes results in orbitally variable X-ray emission. Most have minimum companion masses which are well below what would be expected for a white dwarf and can be classified as black widows, but two have minimum masses in the 0.05-0.1 solar mass range bridging the black widows and redbacks. This program will significantly increase the number of observed systems helping us characterize the range of X-ray behavior as well as further explore the dependence on the companions. properties. UV observations with the optical monitor will complement planned optical observations with the LCOGT network.

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.
