The discovery of three millisecond pulsars (MSPs) swinging between an accretionand rotation powered states has provided evidence for the existence of apeculiar evolutionary phase of binary pulsars. These sources are known as.transitional. MSPs (tMSPs). We have recently identified the source CXOUJ110926.4-650224 as a strong tMSP candidate. We propose simultaneous high-timeresolution observations of this system using XMM-Newton (20 ks) and the VLTHAWK-I (3.5 hr) to\: (i) search for correlations or anti-correlations betweenthe X-ray and near infrared emissions down to time scales of tens of seconds and(ii) understand the mechanism of mode switching and (iii) whether it operates inall the tMSPs.

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.
