|Title||Spin Period Changes of Isolated Neutron Stars|
|Author||Dr Frank Haberl|
|Description||We propose XMM-Newton observations of two pulsating isolated neutron stars, INSs, for which no precise spin period and no period derivative are determined yet. A monitoring program will allow to derive these fundamental parameters with high accuracy and perform detailed pulse phase spectroscopy and pulse profile modelling. The XMM-Newton observations of the pulsars RXJ0420.0-5022, 22.69 s, and RXJ0806.4-4123, 11.37 s, will complement the results obtained for the only known other two pulsating INSs RXJ0720.4-3125 and RBS1223 and are crucial for our knowledge of magnetic field and spin evolution of INSs and for our understanding of the whole class of INSs including soft gamma repeaters and anomalous X-ray pulsars.|

|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.
