During a systematic search (the largest ever in the high energy band) forcoherent periodicities in about 400,000 light curves of serendipitous sourcesdetected by Swift X-Ray Telescope (XRT) and Chandra Advanced CCD ImagingSpectrometer (ACIS) we identified (the project is still on-going) 26 new X-raypulsators. In this proposal we ask for XMM-Newton follow-up observations forfive of them, which either show unusual properties or are not covered by furtherarchival data. The requested observations will allow us to unveil their nature.We also expect to identify new classes of neutron stars and white dwarfs and/orextending our understanding of the physics of accretion toward lowerluminosities.

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.
