supernova

Because the evolved supergiant is expected to eventually end its life in a supernova explosion, the dramatic dimming prompted speculation that the star might be preparing to explode.

Very massive stars can end their lives in supernova explosions, but such events are relatively uncommon.

Scientists initially classified the object as a supernova remnant, but that interpretation became less certain after emissions above 100 TeV were detected.

The team also used supernova models to explore how this explosion mechanism could contribute to galactic chemical enrichment.

The awesome supernova explosion ejects into space most of the matter of the precursor star—a little residual hydrogen and helium and significant amounts of other atoms, carbon and silicon, iron and uranium.

Measurements of Type Ia supernovae were central to the discovery that the expansion of the universe appears to be speeding up, a breakthrough recognized with the 2011 Nobel Prize in Physics.

However, the South Korean study published last year challenged it by arguing that Type Ia supernovae did not all reach the same peak brightness as the universe aged.

Their results showed that PBH-triggered SNe Ia could reproduce several characteristics observed in these supernovae and their remnants.

Instead of fading smoothly, as most supernovae do, its brightness rose and fell repeatedly.

All those recently hatched massive blue- white super-giant stars in Orion are destined in the next few million years to become supernovae, a continuing cosmic fireworks in the constellation of the hunter.

"Our prediction is that we'll see a lot more galactic cosmic radiation... which is from supernovas and is everywhere," versus radiation coming from the Sun, he said.

So, is the theory wrong and heavy elements are produced some other way, or are they only produced in supernovas under certain conditions?

From BBC ● Apr. 12, 2024

Long duration GRBs are caused by supernovas, the point when a massive star reaches the end of its life and explodes into a burst of light.

From Science Daily ● Feb. 29, 2024

Ever since, neutrinos have been detected in the Sun, during supernovas and even in interactions between cosmic rays and the upper atmosphere.

From Salon ● Aug. 31, 2023

In late 1997 astronomers announced that they had used these supernovas to measure the distance to some very dim and ancient galaxies.
