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

The Ztrack source Cygnus X2 has relativistic jets essentially in only one ofits three states allowing us to find conditions at the inner disk needed for jetformation. The applicants recently made breakthroughs, proposing from continuumanalysis a model for the Ztrack and jet formation and secondly mapping highlyionized ADC line features around the Z indicating that the mass accretion rateincreases in the sense opposite to that shown by the continuum. The crux ofunderstanding the 3 states, jet formation and line formation in the ADC isfinding the direction of Mdot increase and we propose to do this by obtainingthe evolution of continuum and lines over a complete Ztrack movement with XMMand Chandra. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
