Line identifications in the spectrum of Lupi A
Abstract
We present new abundance determinations for the sharp-lined HgMn star Lupi A from archival FEROS spectra. Selected unblended lines with accurate atomic data have been synthesized to derive new abundances for Lupi A. These spectra show evidence of the presence of blue-shifted lines of the companion Lupi B. The synthesis of the spectrum of Lupi B confirms that this star is cooler, probably an early A star with normal abundances.
