Title: New Wolf-Rayet central stars of planetary nebulae identified on the AAO/UKST H<i>α</i>Survey
Abstract: The central stars of two of the new planetary nebulae found during scans of the AAO/UKST Hα Survey of the Milky Way have been found to exhibit Wolf—Rayet (WR) emission features. One (PMR 1) is an early-type star of class either [WO4] or [WC4]. The other (PMR 2) is a late [WC] star which, depending on the classification scheme used, is either intermediate in class between [WC9] and [WC10] or the sole member of the [WC10] class. Both stars exhibit unusual spectral features which may be attributed to enhanced nitrogen in their atmospheres and could be indicative of unusual stellar evolution.
