Emission lines in the spectrum of the 3He star 3 Centauri A.

Abstract (from CDS):

Emission in the 4d⟶4f transitions of Mn II (multiplet 13, λλ6122-6132), in the 4f⟶6g transitions of P II, and in λ6149.5 of Hg II has been detected in the spectrum of the helium-weak star 3 Centauri A (B5 III-IVp). Weaker emission from the same Mn II multiplet is also seen in the hot, mild HgMn star 46 Aquilae (B9 III). It is suggested that the emission is of photospheric origin and may be evidence for the stratification of manganese, phosphorus, and mercury in the photosphere of 3 Cen A and of manganese in 46 Aql.
