| Abstract | Understanding the 3D structure of disc winds is vital for constraining theirenergetics, but in most sources, we only have one sightline through the wind.Her X-1 is a unique X-ray binary with a warped precessing disc, providing timevariable sightlines. A disc wind was detected during Her X-1 Main High state,varying in time due to the changes in our sightline over the precession cycle.Hence, we can uniquely sample the vertical wind structure, seen to weaken atgreater heights above the disc. An archival Short High state observation shows astronger wind than those during Main High - we are sampling lower wind heightsabove the disc. We propose 3x80 ks XMM and 1x25 ks Chandra exposures duringShort High, to understand the 3D wind structure at all heights and constrain its energetics. |

| 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. |
