We propose to perform two 170 ks INTEGRAL ToO observations of a transientmillisecond X-ray pulsar in outburst. To constrain the broadband spectrum wealso request one 30 ks simultaneous NuSTAR and two 50 ks XMM-Newtonobservations. The target can be either one of the fifteen known transientaccreting millisecond X-ray pulsars (AMXPs) in the case of a new outburst or anewly observed object of this class. These observations allow us to study thebroad band spectrum in detail from hard to soft X-ray energies as well as thetiming properties or eclipsing features of the source during its outburst. Wewill detect type-I X-ray bursts, and/or for the first time also burstoscillations at high-energy (if present).

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.
