Spectrum from FEROS of HD 327083 taken on 2017, August 26 (solid black line) compared with MARCS atmospheric models of 6600–6750 K for log g = 2.0 and log g = 3.5 (solid green and red lines, respectively). This region is dominated by photospheric lines (of H I and metals) from a late F-type star. The emission lines are formed in the disc of the hot companion: He I (P Cygni profiles), Hα, and Fe II lines.
