|Title||The First X-ray Observations of Four Exotic New Millisecond Pulsars|
|Author||Prof David Kaplan|
|Description||We have discovered four nearby, exotic millisecond pulsars: one is a unique triple system; another orbits a very low-mass companion every 96 min; the others are part of Pulsar Timing Arrays. As such all of these pulsars will be the targets of considerable multi-wavelength observations over the next few years. Soft X-ray observations of millisecond pulsars are vital to understanding their thermal emission, neutron star heating, particle emission, and fundamental parameters such as mass and radius. We request 60 ks of XMM observations to detect the X-ray counterparts of these pulsars. By measuring their luminosities and temperatures we will help determine the efficiency of polar cap heating, and can plan for detailed phase-resolved observations.|

|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.
