What the Awkward Relatives Tell Us about Planetary Nebulae Hosting Binary Systems
Published online by Cambridge University Press: 15 December 2006
Abstract
Relatives to Planetary Nebulae, such as barium stars or symbiotic systems, can shed light on the connection between Planetary Nebulae and binarity. Because of the observational selection effects against direct spectroscopic detection of binary PNe cores with orbital periods longer than a few dozen days, at present these “awkward relatives” are a critical source of our knowledge about the binary PNe population at longer periods. Below a few examples are discussed, posing constraints on the attempts to model nebula ejection process in a binary.
