Query: A Monte Carlo Study of the Spectra from Inhomogeneous Accretion Flow   The model of inhomogeneous accretion flow, in which cold clumps are
surrounded by hot gas or corona, has been proposed to explain the spectral
features of black hole X-ray binaries (BHXBs). In this work, we try to find
possible observational features in the continuum that can indicate the
existence of clumps. The spectra of inhomogeneous accretion flow are calculated
via the Monte Carlo method. Since the corresponding accretion flow is unsteady
and complex, the accretion flow is described by a set of free parameters, the
ranges of which can include the real cases. The influences of the parameters
are investigated. It is found that the thermal component of the spectra
deviates from the multi-color black body spectra in the middle power-law part.
On the one hand, a warp appears due to the gap region between the clumps and
the outer cold disk, and on the other hand, the slope of the line connecting
the thermal peaks deviates from 4/3. The warp feature, as well as the
correlation between the thermal peak at higher frequency and the spectral
index, are possible to indicate the existence of clumps, and are worthy of
further investigation with more self-consistent models.
