Abstract 1RXS J050526.3-684628 is a super soft source (SSS) in the Large Magellanic Cloud(LMC). A recent study reported the discovery of coherent pulsations, andidentified the system as an accreting White Dwarf (WD). Moreover, the study ofhistoric X-ray and optical properties of J050526 have revealed it to be aremarkably long-lived post-nova SSS (~30 year duration), reaching its peak fluxaround 2013. Nevertheless, the lack of multiple deep X-ray observations hampersthe study of the system and prohibits further testing of theoretical models. Werequest a 60 ks XMM-Newton observation to study the evolution of its spectraland temporal properties during the decay of its flux.

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.
