Abstract

A detailed abundance analysis has been carried out for the Hg-Mn star 46 Aql using high-resolution spectra in the visual region (5100-6400 Å) obtained with the High Dispersion Spectrograph of the Subaru Telescope. Our attention has been mainly focused on those elements which have not been analyzed previously. He, C, N, and O are underabundant, while Na shows the solar abundance. We have confirmed previously reported underabundances of Mg, Al, and Si, and have found an overabundances of P (+1.5dex) and Ti (+ 1.0dex) and a significant underabundance of S (-1.8dex). Fe is overabundant by +0.8±0.1 dex and a microturbulent velocity of 0.3kms^-1 was found from an analysis of the Fe II lines. Among a few hundred unidentified absorption lines, we identified lines of As II and Xe II and a very large (+4.0dex) overabundance of Xe is obtained. We have confirmed emission lines of Mn II and Ti II near 6100 Å, while those of Cr II cannot have been seen.
