The interpretation of MnII emission from late-type B stars.

SIGUT T.A.A.

Abstract (from CDS):

The photospheric MnII emission lines Wahlgren & Hubrig (2000A&A...362L..13W) detect in the spectra of several late-type B and HgMn stars and attribute to fluorescent excitation are more naturally explained by interlocked non-LTE effects acting in a photosphere in which the manganese abundance is stratified with depth. The case is particularly strong for HD 186122 (46 Aql) and HD 179761 both of which require the manganese overabundance to be concentrated to column masses of log(m)≤~-1.5.
