Post-RGB Planetary Nebulae
Abstract
At least 20% of PNe host a post-common-envelope central star, and theoretical considerations predict that a significant fraction of these should come from common envelopes during the RGB (as opposed to the AGB). However, only a handful of candidate post-RGB PNe are known. Here, we present the discovery of a new post-RGB binary central star - discovered as part of a concerted effort to discover and characterise binary central stars of planetary nebulae in order to further our understanding of the common-envelope phase.
