|Title||XMM SEARCH FOR PROTON CYCLOTRON FEATURES IN IN THE AXP 4U0142+614|
|Author||Dr NANDA REA|
|Description||The ..magnetar. model, proposed to account for the nature of the X-ray emission from AXPs, assume that these sources are powered by magnetic field decay of a magnetic field strength of >10^14 Gauss. If the magnetar scenario is correct, proton cyclotron features (PCFs) are expected to lie in the X-ray band. We propose an XMM observation of the 4U0142+614, the brightest source of this class of pulsars. The present request is first aimed at searching for an absorption feature due to proton cyclotron scattering, that would allow us to finally infer its magnetic field strenght. Secondly, we will study the link between timing and spectral properties. Finally, we will check for the presence of a broad spectral feature we marginally detected during a ASCA 2001 observation.|

|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.
