Abstract	We request a 50 ks observation of a pulsating (P~170 s), accreting white dwarfbinary located in the Large Magellanic Cloud. The system was serendipitouslydetected off-axis during analysis of an archival XMM-Newton observation (2013)that was severely contaminated by high background. Such objects are thought tobe candidates for the progenitors of type Ia supernovae, or may alternativelyundergo accretion-induced collapse to form the neutron stars in some millisecondpulsars. The nature of their short period oscillations remains unknown. Theon-axis XMM-Newton observation proposed below would deliver a much improvedspectrum, allowing precise characterisation of the system.

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.
