Spectral state transitions in low-mass X-ray binaries - the effect of hard and soft irradiation [PDF]
, 2005 In neutron star and black hole X-ray binaries the transitions between the two spectral states, hard and soft, signal the change between accretion via a hot advection-dominated flow(ADAF) and disk accretion.
