Abstract	The binary AR Sco is the rst radio pulsar driven by a white dwarf, rather than aneutron star. From searches of the Gaia database, we have identi ed a new systemwith a very similar spectral energy distribution to that of AR Sco, at a similardistance. We propose an observation of 20 kiloseconds to uncover the nature ofthis new binary and determine whether it is the second member of the white dwarfpulsar class.

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.
