| Abstract | Analysis of the first 20-ks Chandra observation of the bright radio-quiet Fermipulsar J0633+0632 reveals an absorption feature in its spectrum near 0.8 keV.Besides that, it is likely the coldest neutron star at the neutrino coolingstage. However, a low number of source counts in Chandra data does not allow toconstrain the line shape and the thermal continuum origin. We propose deepobservations with XMM-Newton to establish the absorption feature shape, toexplore the continuum, and to search for X-ray pulsations with the pulsarperiod. |

| 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. |
