Description We propose XMM-Newton and NuSTAR observations of PSR B0656+14. Its X-ray spectrum shows complex variability with the pulsar.s rotation phase. Our re-analysis of archival data suggests that much of the variability could be due to spectral feature(s) rather than a hot polar cap. If confirmed, it would only be the second case when such features are seen in the spectrum of a rotation-powered pulsar. The origin of the features must be intimately linked to the properties of NS atmospheres or magnetospheres. However, one should study the features in more than one pulsar before a definitive interpretation can be given. In addition, our observations will fill in the gap in the multiwavelength spectrum of B0656+14 by measuring its non-thermal spectrum above 6 keV.

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.
