标题： IrOnIc: How to Consider Hundreds of Millions of Iron-Group Lines in NLTE Model-Atmosphere Calculations

摘要： 铁族元素具有非常高的原子能级数量和大量光谱线。 没有任何非局部热平衡模型大气代码可以以传统方式处理这些。 在过去十年中开发了一种统计方法，以将能级和线数减少到可管理的数量。 铁 opacity 和界面（IrOnIc）计算采样的截面和模型原子文件，作为模型大气计算的输入。 IrOnIc 目前正在被转换为并行化代码，以将计算时间减少到合理值。 它将作为德国天体物理虚拟天文台的服务向公众开放。 显示英文摘要

摘要： 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.
