面向G191-B2B和其他DA类型对象的标准化行列表

Towards a standardised line list for G191-B2B, and other DA type objects

Simon P. Preval, Martin A. Barstow, Jay B. Holberg, N J. Dickinson

摘要:

我们提出了一个全面的分析G191-B2B的远紫外光谱在900- 1700 nm的范围内使用共同添加的数据从FUSE和STIS档案。虽然Holberg等人(2003年)以前的鉴定在这项工作中得到了重申,但发现许多以前未鉴定的谱线现在可以归因于Fe,Ni和一些较轻的金属。未来的工作包括将这种详细的分析扩展到更广泛的DA对象,期望能够实现对其大气层的更完整的分析。

英文摘要:

We present a comprehensive analysis of the far UV spectrum of G191-B2B over the range of 900-1700Å using co-added data from the FUSE and STIS archives. While previous identifications made by Holberg et al. (2003) are reaffirmed in this work, it is found that many previously unidentified lines can now be attributed to Fe, Ni, and a few lighter metals. Future work includes extending this detailed analysis to a wider range of DA objects, in the expectation that a more complete analysis of their atmospheres can be realised.
