Physics & Radiative Transfer

Various physical concepts are incorporated into SIROCCO. Some of these are descibed below. We also recommend consulting Matthews, Long et al.

• Radiative Transfer Modes
  • Sobolev Approximation
  • Classic v Hybrid macro-atom mode
  • Macro-atoms and 2-level-atoms
  • Isotropic v Anisotropic Line Scattering
  • Doppler Shifts and The Comoving Frame
• Macro Atoms
  • A Hybrid Scheme
  • Macro-atom Emissivity Calculation
  • Bound-free Continua of Simple Atoms
• Special Relativity and Co-Moving Frames
• Anisotropic Scattering
  • Anisotropy within the viewpoint technique
• Limitations and Caveats
  • Specific issues and code problems
  • Conceptual and Practical difficulties
