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

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.
