Description The non-thermal hard X-rays of magnetars are a crucial key to understand their magnetic activities,or even a unique way to access the toroidal magnetic field hidden inside a stelar interior. A new signature of stellar free precision has been suggested from two sources 4U 0142+61 and 1E 1547.0-5408. This can be interpreted as a distortion of stellar shape due to the extremely strong toroidal field of magnetars. However, the results are only limited to Suzaku observations from a few sources. It is hence imperative to confirm whether such a signature does exists in other magnetars from NuSTAR observations. We propose a 120 ks observation of a prolific soft gamma repeater SGR 1900+14 which hard X-ray timing and spectral nature has yet to be investigated in detail.

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.
