Figure 1: Internal rotation rate of our model 3.0M ⊙ asymptotic-giant-branch star as a function of radius near the base of the convection zone. Detection of X-rays from such a corona is unlikely ...

Of the many different kinds of stars, asymptotic giant branch (AGB) stars, usually slightly larger and older than our own sun, are known producers of interstellar dust. Dusty AGBs are particularly ...

Asymptotic giant branch -- AGB -- phase stars, near their end of life, are particularly significant sources of such substances in our galaxy. Stars like our Sun eject large amounts of gas and dust ...

The circumstellar envelopes (CSE) of asymptotic giant branch (AGB) stars contain a large number of molecules, which account for about one-third of all molecules discovered in interstellar space.

Other potential sources of fluorine that scientists have considered include asymptotic giant branch stars, which are pulsing stars with masses a few times that of our sun. But the evolution of ...
