| Description | The nearby, middle-aged neutron star PSR B1055-52, one of the so-called Three Musketeers, has been observed once by XMM-Newton in 2000 resulting in a detailed phase-resolved spectral analysis. Chandra observations in 2012 show spectral changes and an apparent >30% flux decrease with respect to the 2000 XMM-Newton observation. These changes are too large to be due to cross-calibration problems. We propose new XMM-Newton observations to probe the apparent spectral changes. Using a better suited instrument mode than the 2000 observations, we will also be able to measure more accurately the magnetospheric spectral component and relate it to the radio and gamma-ray pulse profiles. Furthermore, we will search for phase-dependent absorption features in the new epoch data. |

| 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. |
