| Abstract | We propose 6 XMM observations of 25 ks each to explore the population ofpersistent LMXB among the faint hard X-ray sources discovered by INTEGRAL.Previous NuSTAR observations showed that diagnostics regularly used to excludeCV identifications may not be sufficient to conclusively identify hard X-raysources. So, we could expect a significant number of magnetic CVs amongidentified persistent LMXBs. We will investigate the true nature of sixpoorly-known sources, and derive the main properties of these systems. Theseresults will help to understand the LMXB population towards low fluxes, bycorrecting their surface density and/or studying the detailed X-ray propertiesof these individual sources. |

| 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. |
