Revisiting the Iron Abundance in the Hyper Iron-poor Star HE 1327–2326 with UV COS/HAT Data

We present a new iron abundance analysis of the hyper metal-poor star HE 1327-2326, based on Fe ii lines detected in its UV spectral range for the first time. In a Cosmic Origins Spectrograph (COS) spectrum, five new Fe ii lines could be measured. A Si i line was also detected for the first time. We...
