Current Code State

Current state of the code

• Radially stratified geometry: Stratified in abundances, density and temperatures

  • Simple geometry with inner boundary emitting black body photons
  • Binning photons and energies after exiting of simulation

• Ionization calculation possible in LTE and Modified Nebular approximation

  • Parametrized by Dilution factor and radiation temperature
  • Main source Abbott & Lucy 1985, Mazzali & Lucy 1993
  • Zetas currently provided by Long et al. (Long & Knigge 2002)

• Excitation calculations possible in LTE and Lucy 1999

  • Lucy 1999: Level divided into meta stable and non metastable
  • Excitation parametrized by Dilution factor (w) and radiation temperature
  • Both partition functions and level populations

• Line interaction possible with scattering, downward branching (to be implemented) and macro atom

  • Macro atom (Lucy 2002) Sobolev escape probability formalism
  • Upwards transitions probabilities scaled with estimated Jbars using W and T_rad
  • No collisional processes included
  • No ionization processes included

• Iterate the model on radiation temperature, dilution factor and inner boundary black body temperature

  • Convergence achieved with different input parameters
  • inner boundary temperature adjusted to achieve given emitted luminosity
