Identified Xe vi (top three rows) and Xe vii (bottom row) lines in the FUSE (λ< 1188 Å) and HST/STIS observations of RE 0503−289. The model (thick, red line) was calculated with an abundance of log Xe = −3.9. The dashed, green spectrum was calculated without Xe. Prominent lines are marked (“is” denotes interstellar origin), and the Xe lines are labelled with their wavelengths given by Gallardo et al. (2015) and in Table B.7.
