Query: A unified accretion-ejection paradigm for black hole X-ray binaries.
  III. Spectral signatures of hybrid disk configurations   It has been suggested that the cycles of activity of X-ray Binaries (XrB) are
triggered by a switch in the dominant disk torque responsible for accretion
(paper I). As the disk accretion rate increases, the disk innermost regions
would change from a jet-emitting disk (JED) to a standard accretion disk (SAD).
While JEDs have been proven to successfully reproduce hard states (paper II),
the existence of an outer cold SAD introduces an extra non local cooling term.
We investigate the thermal structure and associated spectra of such a hybrid
disk configuration. We use the 2T plasma code elaborated in paper II, allowing
to compute outside-in the disk local thermal equilibrium with self-consistent
advection and optically thin-to-thick transitions, in both radiation and gas
supported regimes. The non-local inverse Compton cooling introduced by the
external soft photons is computed by the BELM code. This additional term has a
profound influence on JED solutions, allowing a smooth temperature transition
from the outer SAD to the inner JED. We explore the full parameter space in
disk accretion rate and transition radius, and show that the whole domain in
X-ray fluxes and hardness ratios covered by standard XrB cycles is well
reproduced by such hybrid configurations. Precisely, a reasonable combination
of these parameters allows to reproduce the 3-200 keV spectra of five canonical
XrB states. Along with X-ray signatures, JED-SAD configurations also naturally
account for the radio emission whenever it is observed. By varying only the
transition radius and the accretion rate, hybrid disk configurations combining
an inner JED and an outer SAD are able to reproduce simultaneously the X-ray
spectral states and radio emission of X-ray binaries during their outburst.
Adjusting these two parameters, it is then possible to reproduce a full cycle.
This will be shown in a forthcoming paper (paper IV).
