Unusual Death of Primordial Stars Discovered by Scientists

Primordial Star

A new study from Lawrence Barkley National Laboratory shows that there are primordial stars that died in an unusual way.

Primordial stars grow 55,000 to 56,000 times the mass of Earth's Sun and upon death would explode creating a supernova and completely burning up not even leaving a remnant black hole.

Ke-Jung Chen from University of California said that they found that these stars explode completely instead of becoming a supermassive black hole.

For this study, researchers created a model that mimics primordial supermassive stars using a one-dimensional stellar evolution code called Kepler.

Kepler looks at key processes of nuclear burning and stellar convection of the stars which is relevant for detecting photo-disintegration of elements, electron-positron pair production and special relativistic effects of massive stars.

Through Kepler, researchers found that primordial stars lived about 1.69 million years ago before they become unstable due to relativistic effects that caused them to collapse.

Researchers said that as they collapse the stars begin to rapidly synthesize heavy elements like oxygen, neon, magnesium and silicon.

Through this process the star releases more energy which stops its collapse causing a massive supernova, they added.

They also said that some supermassive stars could explode through an entire host galaxy and expand to some nearby galaxies,

However, some supernova can cause star formation in its host galaxy, which is distinct from other young galaxies.

Researchers also said that they've found a way to show a simulation on what occurred in the life of the star before they exploded.

They believe that their research could create a distinct observational signature that could be detected through infrared.
