X-ray spectral index correlations vs mass accretion rate in neutron star and black hole binaries in their different spectral states. Theory vs observations

Goal of this presentation: «To demonstrate that in X-ray observations there is objective (model independent) information regarding the nature of compact objects. To illuminate status of our results obtained thus far from Galactic black hole (BH) candidates and neutron star (NS) sources and their impact Model independent observational signatures of BH and NS sources.
