| Abstract: |
We report on results of our spectroscopic analysis of five PG1159 stars. The measured abundances of trace elements are in agreement with the intershell composition of Asymptotic Giant Branch stellar models. We also report on our discovery of forbidden components of C IV lines. This is the first detection of forbidden components from elements heavier than helium in astrophysical sources. |
