| Description | Three new transient millisecond X-ray pulsars (TMXPs) have been discovered recently. Together with SAX J1808.4-3658 these transients show peculiar characteristics (beyond pulsations, e.g. orbital periods of virgul40 min) which likely indicate that they form a separate sub-class in between transient neutron star systems. Also in quiescence SAX J1808.4-3658 is peculiar, showing a lower luminosity and the lack of a soft component. These observational facts likely indicate the presence of a massive (>1.7 solar masses) neutron star, confirming the recycling connection between LMXRBs and MSPs. Here we propose to observe the new three TMXPs in quiescence to unveil their properties and to identify similarities and differences with SAX J1808.4-3658. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
