| Abstract: |
Iron-group elements have a very high number of atomic levels and an overwhelming number of spectral lines.
No NLTE model-atmosphere code can cope with these in a classical way.
A statistical approach was developed over the last decade
to decrease the number of levels and lines to a manageable amount.
The Iron Opacity and Interface (IrOnIc)
calculates sampled cross-sections and model-atom files as input for model-atmosphere computations.
IrOnIc is presently transferred into a parallelized code to reduce
the calculation time to a reasonable value.
It will be accessible by the public as a service of the German Astrophysical
Virtual Observatory. |
