    Scientists observe Mysterious Death of a Star Emitting Six Rings

    March 29, 2022, Categories  Astronomy/Space

    A rendering of the star V Hydrae, or V Hya for short. In its death throes, the star has emitted a series of expanding rings that scientists calculated are being formed every few hundred years, said Mark Morris, a UCLA professor of physics and astronomy.

    Astrophysicists studying in unprecedented detail a red giant star named V Hydrae — abbreviated as V Hya — have witnessed the star’s mysterious death throes.

    Researchers from UCLA and NASA’s Jet Propulsion Laboratory discovered that the carbon-rich star has expelled six slowly expanding molecular rings and an hourglass-shaped structure ejecting matter out into space at high speeds, signaling that the star is undergoing rapid evolution as it ends its life in a blaze of glory before shutting down its energy production.

    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.
