Observational identification of a sample of likely recent Common-Envelope Events
Theo Khouri, Wouter Vlemmings, Daniel Tafoya +5
One of the most poorly understood stellar evolutionary paths is that of binary systems undergoing common-envelope evolution, when the envelope of a giant star engulfs the orbit of…
High-resolution observations of IRAS 08544-4431. Detection of a disk orbiting a post-AGB star and of a slow disk wind
V. Bujarrabal, A. Castro-Carrizo, H. Van Winckel +4
We are studying a class of binary post-AGB stars that seem to be systematically surrounded by equatorial disks and slow outflows. Although the rotating dynamics had only been well…
Strong Variable Ultraviolet Emission from Y Gem: Accretion Activity in an AGB Star with a Binary Companion?
Raghvendra Sahai, James D. Neill, Armando Gil de Paz +1
Binarity is believed to dramatically affect the history and geometry of mass loss in AGB and post-AGB stars, but observational evidence of binarity is sorely lacking. As part of a…
