Title The mechanism of jet formation in Cyg X-2 and the nature of the hot ADC

Author Dr Michael Church
Description The Z-track source Cygnus X-2 has relativistic jets essentially in only one of its three states allowing us to find conditions at the inner disk needed for jet formation. The applicants recently made breakthroughs, proposing from continuum analysis a model for the Z-track and jet formation and secondly mapping highly ionized ADC line features around the Z indicating that the mass accretion rate increases in the sense opposite to that shown by the continuum. The crux of understanding the 3 states, jet formation and line formation in the ADC is finding the direction of Mdot increase and we propose to do this by obtaining the evolution of continuum and lines over a complete Z-track movement with XMM and Chandra.

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.
