Synthetic spectra compared to our observations. Left: comparison of the observed Hδ line (black dots) from the mean low-〈B〉 spectrum of HD 57372 to solar abundance synthetic spectra (coloured curves) covering a range of Teff and log g. Right: similar to the left panel but with the blue curve showing the solar abundance synthetic spectrum with the adopted Teff = 13 500 K and log g = 4.0 and the red curve being the same but with abundances adjusted as quoted in Table 3.
