Abstract
In this work we present the results of a high-resolution spectroscopic study of Feh-Duf star [4]. We determine its abundance pattern and discuss the evolutionary state and a possible extragalactic origin of this star.

Notes
- 1.
In this work, we use the standard spectroscopic abundance notation \(\log \epsilon (\mathrm{X}) =\log ({N}_{\mathrm{X}}/{N}_{\mathrm{H}}) + 12\) and [X/H]\(=\log {({N}_{\mathrm{X}}/{N}_{\mathrm{H}})}_{{_\ast}}-\log {({N}_{\mathrm{X}}/{N}_{\mathrm{H}})}_{\odot }\). The solar abundances are from [6].
