  High-sensitivity X-ray polarimetric observations of black hole X-ray
binaries, which will soon become available with the launches of space-borne
X-ray observatories with sensitive X-ray polarimeters, will be able to put
independent constraints on the black hole as well as the accretion flow, and
possibly break degeneracies that cannot be resolved by spectral/timing
observations alone. In this work we perform a series of general relativistic
Monte-Carlo radiative transfer simulations to study the expected polarization
properties of X-ray radiation emerging from lamp-post coronae in black hole
X-ray binaries. We find that the polarization degree of the coronal emission of
black hole X-ray binaries is sensitive to the spin of the black hole, the
height of the corona, and the dynamics of the corona.
