Description Among the unassociated sources detected by the Fermi Gamma-ray Space Telescope, we find one 2.5-hr binary from our multi-wavelength studies. The source, with an X-ray counterpart, has an optical spectrum typical of accretion disks in X-ray binaries, and thus is likely a transitional millisecond pulsar (MSP) system in the disk state. Such systems can switch between the states of being a pure MSP and having an accretion disk around the MSP. Here we request an 11-ks observation of the source for further studies. A spectrum of the source will be obtained to check whether its X-ray emission is consistent with those of redback type of MSPs. We will also search for fast and large-amplitude flux variations, which is a distinguishing feature of the transitional systems in the disk state.

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.
