Determination of the Abundance of Mercury from the Hg II Line at 5677.10 Å in Late B-type Stars. XII. HD 7374 (87 Psc).

Abstract (from CDS):

The weak line of Hg II located at 5677.10 Å is not detected in a coadded ELODIE spectrum of the HgMn star HD 7374 which may be explained by the decrease of the signal-to-noise ratio in the red part of the spectrum. The synthesis of various spectral intervals yields several new measurements of the abundances of helium, carbon, oxygen, magnesium, aluminum, silicon, titanium, chromium, manganese, iron, nickel, gallium and yttrium. Most of these new measurements agree well with previous measurements.
