Abundance patterns of LS IV–14°116 and Feige 46 relative to that of the Sun (by number fraction). Only elements with an abundance measurement are shown. Upper limits are marked with an arrow and less saturated colours. For comparison, abundance measurements for He-poor sdOB stars (33000 K < T_eff < 36500 K) are shown as grey open circles (Geier 2013, based on optical data), diamonds (Chayer et al. 2006, based on far-UV data), and squares (O’Toole & Heber 2006, based on UV data).
