| Description | We propose a series of four 20 ks observations with NuSTAR and XMM of the Galactic binary X-ray pulsar Hercules X-1, which has a 35 day superorbital period caused by a warped, precessing accretion disk. The hard beam from the neutron star heats this disk and the corresponding reprocessed, thermal emission provides a unique opportunity for observation of magnetic-dominated accretion. Our proposed analysis requires good spectral and timing resolution across the full energy band (<1 keV to >20 keV) in order to constrain both the soft emission from the disk and the pulsar beam. For the first time, we will track a complete precession of Her X-1a??s accretion disk with full hard X-ray coverage to gain the clearest picture to date of the structure and kinematics of the magnetized accretion flow. |

| 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. |
