Observations at various wavelengths of late B-type stars exhibiting strong overabundances of the chemical elements Hg and Mn in their atmospheres indicate that these stars are frequently found in bina...
3D hydrodynamical CO5BOLD model atmospheres of late-type giants: chemical abundances from molecular lines
Solar and Stellar Astrophysics (astro-ph.SR)
