Title Extending the XMM-Newton survey of AM CVn systems to longer periods


DOI 10.5270/esa-3bl8p45
Author Dr Gavin Ramsay
Description We have an on-going project to survey the ultra-compact AM CVn systems using XMM-Newton. These accreting binaries have periods less than ~70 min and are hydrogen deficient. They are important astrophysically because they are expected to be strong sources of gravitational radiation in the peak sensitivity band of LISA. XMM-Newton has so far observed 7 of the 13 AM CVn systems, but this is biased towards shorter period systems. We propose to observe another 4 systems to give us a comprehensive sample of these objects. In particular, we will determine the element abundance from their X-ray spectra and characterise the X-ray and UV variability as a function of orbital period. This is essential for our understanding of their evolutionaryhistory and their energy balance.

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.
