Accretion inevitably produces disk winds, which has vast consequences. Theseoutflows can regulate the accretion process, affect the long-term orbitalevolution of the X-ray binary, and impact their cosmic environment. However, itis not established exactly how disk winds are launched, and how much mass iscarried away by them. We propose to study the disk wind of a persistentlyaccreting neutron star across the electromagnetic spectrum with XMM-Newton, HSTand VLT. These simultaneous multi-wavelength data will determine the launchmechanism and mass content of the disk wind. This show-case study will highlightthe impact of studying disk winds across the electromagnetic spectrum and pavethe way for future observing programs.

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.
