Space, science and astronomy red giant

For the first time in the history of astronomy, a team of scientists observed the death of a red supergiant, the rapid self-destruction and massive torment of the star before it transformed into a Type II supernova.

Researchers at Northwest University and UC Berkeley note that the star is ten times the size of the Sun, Within 130 days that preceded the explosion.

They were thought to have been relatively calm before their death, with no evidence of violent volcanic eruptions or luminous emissions. in a new notesHowever, he discovered bright radiation from the star in his final year.

Scientists observe for the first time the explosion of a dying star. Astronomers observed the star for 130 days. The giant red giant is 10 times the mass of the Sun and is located 120 million light-years from Earth in the galaxy NGC 5731.

The Pan-STARRS Telescope of the University of Hawaii’s Institute of Astronomy first detected the massive star in 2020 thanks to its massive mass. amount of light emitted by the red giant. A few months later, a supernova lit up the sky.

Raffaella Margotti, a co-author on the study, noted: “We’ve never seen such violent activity in a dying red giant star. It produced a bright emission before collapsing and burning.” published Na Revista Astrophysical Journal.

This activity indicates that at least some of these stars must undergo significant changes in their internal structure, resulting in the appearance of the star noisy gas dischargeMoments before it collapses.

The lead author of the research, Wynn Jacobson-Galán, commented that it is “a significant advance in understanding what is happening with huge stars Moments before their death.”
