Fig. 2
Section of the HST/STIS spectrum, compared with models with different log g of 7.0 (thin, green, dashed), 7.5 (thick, red), and 8.0 (thin, blue, dashed) and Teff = 70000 K. The synthetic spectra are normalized to match the flux of the observation at 2800 Å, respectively. All spectra are convolved with Gaussians (full width at half maximum of 1 Å) for clarity. Identified lines are indicated. “is” denotes interstellar origin.
