ALMA catches dying star mid-transformation with ring from outburst
Astronomers utilizing the Atacama Large Millimeter/submillimeter Array (ALMA) have captured a dying star in the midst of a dramatic transformation. The newly analyzed data reveals a distinct ring structure that physically records the star's final explosive outburst. The findings were detailed in a research paper uploaded to the arXiv preprint server and accepted for publication in The Astrophysical Journal, offering unprecedented insight into stellar evolution during its terminal phases.
