Abstract | Until recently spectral features had been found only in X-ray Dim IsolatedNeutron Stars (XDINSs), Rotating Radio Transients (RRATs), magnetars, andCentral Compact Objects (CCOs) in SNRs, which all are exotic members of theknown neutron star population dominated by rotation-powered pulsars. In our EPICobservation of an ordinary 100-kyr-old pulsar J1740+1000 we unexpectedly foundsolid evidence for absorption features in an isolated rotation-powered pulsar.We request a much deeper observation to study the features in detail, measurethe phase-dependent changes in the feature energies, widths and depths, andestablish their physical nature. These findings will have far-reachingimplications for understanding the physics of NS magnetospheres and atmospheres. |

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. |
