Kr vi lines and one Kr vii line (bottom right) identified by Werner et al. (2012b) in the observed FUSE spectrum of RE 0503−289. Three synthetic spectra are overplotted. Thin, blue: the genuine spectrum of Werner et al. (2012b, T_eff = 70000 K, classical Kr model atom with log Kr = −4.3. Thick red (T_eff = 70000 K): our new Kr model atom with log Kr = −4.3. Dashed, red (T_eff = 70000 K): our new Kr model atom with log Kr = −3.3. Kr lines are indicated with their wavelengths from Tables A.11 and A.12, and other lines by their ion’s name. “is” denotes interstellar origin.
