Scientists see a red giant heading for the supernova for the first time


Although there are countless stars in the heavens, one can see one in the path of a supernova it is still a very rare event. Now, the astrologers have said arrested supergiant red before, during and after the supernova eruption for the first time, collection new innovations of these major events.

“This is crucial to our understanding of what the great stars do before they die,” said lead author Wynn Jacobson-Galán (UC Berkeley). “The direct detection of pre-supernova events in the deep red star has never been seen in a typical Type II supernova. For the first time, we saw a bright red star explode!”

Application Pan-STARRS telescope in Maui, Hawai’i, scientists have detected a red star that is about to be destroyed by the summer of 2020 due to the intense light emitting. Later in the autumn when it went supernova, the team caught a strong flash using Hawaii-based Keck Observatory‘s Low Resolution Imaging Spectrometer (LRIS). He also recorded the first supernova version, known as SN 2020tlf.

His findings suggest that the star must have emitted a number of spheres before the explosion. Previous experience has shown that red giants were calm before heading to the supernova, so these new ones show that some can change their inner appearance before the eruption. This can cause turbulence to release gas before it collapses.

SN 2020tlf is in the galaxy NGC 5731 about 120 million light years from Earth and was 10 times larger than the Sun. The stars go to the supernova when they run out of fuel and fall on their gravitational force, resulting in a huge explosion of carbon fusion. To achieve this, they must be large enough (8 to 15 solar mass) or just fall into a white star if our Sun eventually falls. Anything bigger than that and can fall into a black hole.

This discovery will allow scientists to study the red supergiant stars in search of similar types of bright rays that may also indicate another supernova. “Recognizing many phenomena such as SN 2020tlf will have a profound effect on how we describe the last months of astronomy … in an attempt to unravel the mystery of how big stars destroy the last moments of their lives,” said Jacobson-Galán.
