Towards a standardised line list for G191-B2B, and other DA type objects
Abstract
We present a comprehensive analysis of the far UV spectrum of G191-B2B over the range of 900-1700 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.
