The iron abundance in helium star HD 144941 *
Received 14 October 1996 / Accepted 29 October 1996
The iron abundance in the helium star HD 144941 has been measured from ultraviolet Fe III lines. It is dex below solar and confirms the low metallicity () previously determined from measurements of CNO and other light elements. The result is important because the low CNO metallicity must be reflected in the iron-group elements in order to explain why HD 144941 does not show pulsations.
