|Title||Searching for the r-modes in Fast Millisecond Pulsars|
|Author||Dr Tod Strohmayer|
|Description||Neutron star observables influenced by r-mode physics, such as their spin and thermal evolution, can potentially provide a unique window on their extreme interiors. We propose to observe several fast spinning, but non-accreting MSPs (PSRs J1902-5105 and J2043+1711) to constrain their core temperatures and r-mode amplitudes. Recent results suggest r-modes are present at very low levels in some of these objects. Either the modes are efficiently damped by an as yet undetermined mechanism, or current calculations of the r-mode instability window may require substantial modification. Since both the instability window and saturation mechanisms are sensitive to spin rates, our proposed observations will provide clues to both of these possibilities.|

|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.
