| Description | We request a 50 ks observation of a pulsating (Pvirgul170 s), accreting white dwarf binary located in the Large Magellanic Cloud. The system was serendipitously detected off-axis during analysis of an archival XMM-Newton observation (2013) that was severely contaminated by high background. Such objects are thought to be candidates for the progenitors of type Ia supernovae, or may alternatively undergo accretion-induced collapse to form the neutron stars in some millisecond pulsars. The nature of their short period oscillations remains unknown. The on-axis XMM-Newton observation proposed below would deliver a much improved spectrum, allowing precise characterisation of the system. |

| 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. |
