| Abstract | PSR J1653-0158 is exceptional, with the shortest orbital period of any pulsarbinary, the largest neutron star mass function, and an unusual H-free companionbeing evaporated by pulsar irradiation. Its optical light curve shows aremarkable hard-spectrum veiling flux, likely synchrotron emission from anIntraBinary Shock (IBS) and the PL X-ray spectrum indicates IBS domination inthis band, as well. Measurement of this IBS components light curve and spectrumin the critical UV-X-ray band is the key to modeling the system. Since J1653 isan exemplar of short period binary evolution, and is a major contributor towardsNS mass limits constraining the dense matter equation of state, a sensitive XMM-Newton observation of this source offers an important probe of compact object physics. |

| 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. |
