Researchers at Northwest University and UC Berkeley observed the star, ten times the size of the Sun, during the 130 days before the explosion. Located in the galaxy NGC 5731, approximately 120 million light-years from Earth, the star SN 2020tlf has challenged theories about the behavior of red giants just before their collapse. last moments. Precursor emission, envelope inflation, and increased mass loss preceding the 2020tlf type II luminous supernova. It is believed to have been relatively calm before her death, with no evidence of violent volcanic eruptions or luminous emissions. But new observations revealed bright radiation from the star in its final year, and scientists first observed 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 approximately 120 million light-years from Earth in the galaxy NGC 5731. The University of Hawaii’s Pan-STARRS telescope discovered the first star in 2020 thanks to the huge amount of light emitted by the red giant. A few months later, a supernova lit up the sky. This activity suggests that at least some of these stars must undergo significant changes in their internal structure, giving way to turbulent expulsion of gas, moments before their collapse. Jacobson Gallan commented that it is “a major advance in understanding what happens to massive stars moments before they die.”

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.

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.
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.”
