|Title||Hard X-ray study of the ultra-compact X-ray\r binary 4U 0614+091|
|Author||Dr Jerome Chenevez|
|Description||We propose a dedicated INTEGRAL monitoring program of the ultra-compact X-ray binary and micro-quasar 4U0614+091 to study its emission properties in hard X-rays. 4U0614+091 harbours the closest active X-ray burster, it exhibits variations on different time scales over the electromagnetic spectrum, such as synchrotron jet emission, X-ray flaring states, and thermonuclear X-ray bursts. Moreover, the high energy persistent emission is characterised by a particularly hard (non thermal) X-ray tail. We want to survey the dynamical behaviour, better describe its spectrum in hard X-rays, to follow the evolution of the long term persistent emission variability, and to investigate the activity of shorter time scale processes. We request joint XMM and INTEGRAL observations.|

|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.
