Abstract | We propose XMM-Newton observations of two pulsating isolated neutron stars,INSs, for which no precise spin period and no period derivative are determinedyet. A monitoring program will allow to derive these fundamental parameterswith high accuracy and perform detailed pulse phase spectroscopy and pulseprofile 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 forthe only known other two pulsating INSs RXJ0720.4-3125 and RBS1223 and arecrucial for our knowledge of magnetic field and spin evolution of INSs and forour understanding of the whole class of INSs including soft gamma repeatersand anomalous X-ray pulsars. |

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. |
