The DustI Radiative Transfer, Yeah!
The DIRTY Model
- The DIRTY model is a code for computing the radiative transfer of
photons through dust including the reemission of the energy absorbed
by the dust.
- The radiative transfer is done using Monte Carlo
techniques allowing for arbitrary distributions of photon emitters
(stars, gas, accretion disks, dust) and arbitratry distributions of
the dust (scatterers and absorbers).
- The dust reemission is
calculated using analytic techniques including equilibrium thermal
emission (large particles), non-equilibrium thermal emission
(small particles), and aromatic feature emission (PAH molecules?).
The dust reemission is done self-consistantly with the radiative
transfer which allows for self absorption by the dust.
