A post-AGB star (pAGB, abbreviation of post-asymptotic giant branch) is a type of luminous supergiant star of intermediate mass in a very late phase of...

The asymptotic giant branch (AGB) is a region of the Hertzsprung–Russell diagram populated by evolved cool luminous stars. This is a period of stellar...

star, not just the normal background nebulosity associated with any massive star forming region, and not a planetary nebula formed by a post-AGB star...

a class of pulsating variables known as RV Tauri variables. It is a post-AGB star and a spectroscopic binary about 4,700 light years away. RV Tau was...

Antliae, a post-AGB star in Corona Borealis UX Arietis, a triple star system UX Lyncis, a dim, red-hued star in Lynx UX Tauri, a binary star system LG...

planetary nebulae in Sagitta: NGC 6886 is composed of a hot central post-AGB star that has 55% of the Sun's mass yet 2,700±850 times its luminosity, with...

the table. It may be a thermal-pulsing AGB star, observed in a helium-burning phase instead of a post-AGB star. SS Gem is likely to be a population I...

variable star and spectroscopic binary in the constellation Monoceros. The primary star is an RV Tauri variable, a cool luminous post-AGB star evolving...

silicate carbon star, likely of the J-type. Another evolved star is EP Lyrae, a faint RV Tauri variable and an "extreme example" of a post-AGB star. It and a...

other large cool stars such as immediate post-AGB stars. The RGB stars are by far the most common type of giant star due to their moderate mass, relatively...
