We propose a dedicated INTEGRAL monitoring program of the ultra-compact X-raybinary and micro-quasar 4U0614+091 to study its emission properties in hardX-rays. 4U0614+091 harbours the closest active X-ray burster, it exhibitsvariations on different time scales over the electromagnetic spectrum, such assynchrotron jet emission, X-ray flaring states, and thermonuclear X-ray bursts.Moreover, the high energy persistent emission is characterised by a particularlyhard (non thermal) X-ray tail. We want to survey the dynamical behaviour, betterdescribe its spectrum in hard X-rays, to follow the evolution of the long termpersistent emission variability, and to investigate the activity of shorter timescale processes. We request joint XMM and INTEGRAL observations.

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.
