| Abstract | We propose to observe 10 newly discovered short period binary millisecondpulsars with XMM-Newton. These millisecond pulsar binaries show evidence forinteraction with their low mass companions which sometimes results in orbitallyvariable X-ray emission. Most have minimum companion masses which are well belowwhat 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 blackwidows and redbacks. This program will significantly increase the number ofobserved systems helping us characterize the range of X-ray behavior as well asfurther explore the dependence on the companions. properties. UV observationswith the optical monitor will complement planned optical observations with the LCOGT network. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
