Magnetars form a small group of isolated X-ray pulsars powered by thedissipation of their magnetic energy. The physical mechanism powering theiractivity is currently poorly understood. It is in particular debated whether thelong-term evolution of their outbursts is due to the coolingof the stellar crust, and/or the untwisting of complex magnetic field structuresin the magnetosphere. We propose joint observations with NuSTAR and XMM-Newtonof the latest discovered magnetar in outburst, SGR 1830-0645, to map the thermalstructures on its surface, test the model predictions for magnetar outbursts,and gain insights into the physics of magnetars. emission.

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.
