Abstract IPHAS J190132.77+145807.6, a very highly magnetised, rapidly rotating massivewhite dwarf, is an ideal target of an exploratory study to probe non-thermalX-ray emission processes and thereby to constrain fundamental physicalinteractions. Due to its extreme magnetic field and rotation, conversion ofrotational energy to dipole radiation may be measurable at soft X-ray energies.Its mass close to the Chandrasekhar limit combined with its field strength makesit the most promising target to detect axion-induced keV emission. Even anon-detection would constrain the axions coupling parameters notably better.Given XMM-Newtons high sensitivity in the r^ant energy ranges, a 70kspointing to this unusual white dwarf promises unique insights into so far scarcely observed phenomena.

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.
