Scientists use ALMA to explain aluminum oxide enrichment around AGB stars. Stars like our Sun eject large amounts of gas and dust into space, containing various elements and compounds. Asymptotic giant branch – AGB – phase stars, near their end of life, are particularly significant sources of such substances in our galaxy. Formation of dust around AGB stars has been considered to play an important role in triggering acceleration of stellar wind, but the detailed mechanism of this acceleration has not been well explained.
