Predicting the fate of binary red giants using the observed sequence E star population: Binary planetary nebula nuclei and post-RGB stars

Nie, J; Wood, Peter R; Nicholls, C P


Sequence E variables are close binary red giants that show ellipsoidal light variations. They are likely the immediate precursors of planetary nebulae (PNe) with close binary central stars as well as other binary post-asymptotic giant branch (post-AGB) and binary post-red giant branch (post-RGB) stars. We have made a Monte Carlo simulation to determine the fraction of red giant binaries that go through a common envelope event leading to the production of a close binary system or a merged star....[Show more]
