Title The first broadband study of a NS transient in quiescence with XMM and NuSTAR

Description In quiescence, the soft X-ray spectra of neutron star (NS) Low-Mass X-ray Binary (LMXB) transients most often contain two components: one is due to thermal emission from the NS surface and is reasonably well-understood, while the other is a hard (often very hard) power-law of unknown origin. The upcoming NuSTAR mission will provide the first measurement of the >10 keV spectrum of quiescent NS LMXBs, which, along with XMM-Newton observations, will allow us to discriminate between accretion and pulsar rotation as the energy source for the power-law component. We propose coordinated XMM-Newton-NuSTAR observations of the closest and brightest quiescent system, Cen X-4.

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.
