摘要：We present a new, time dependent, three-dimensional code for modelling the inner regions of
X-ray binaries and AGN, where the photon distribution emitted by the accretion disc evolves simultaneously
with the interacting electron distribution. The HEART (High Energy Astrophysical
Radiative Transfer) code can model many different geometries including a spherical corona and
an inhomogeneous corona. Inverse Compton scattering, bremsstrahlung, synchrotron radiation,
Coulomb interactions, reprocessing of photons by the accretion disk, electron-positron annihilation
and pair production are modelled. Electron distributions may be of power law form, thermal
or a combination. We include some ts to X-ray spectral data and some results already obtained
using the code.
