Millisecond pulsars have boosted in number thanks to the detection of highenergy GeV emission by Fermi. Those in compact binaries with nondegeneratecompanions,the redbacks (RB), challenge the evolutionary link between neutronstar low mass X-ray binary and rotation-powered radio pulsars with 3 systemsfound to transit between the two stages.A new gamma-ray source has been recentlyidentified with the energetic radio pulsar PSRJ1431-4715 in a RB sharingsimilarities with the 3 transitional pulsars. We propose to study for the firsttime the X-ray emission arising from an intrabinary shock between the powerfulpulsar and companion winds to determine the energy budget and the amount ofirradiation of the companion, a key parameter to understand how RBs undergo transitions.

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.
