Planetary experts have located a mysterious origin of one of the luminous explosions ever observed in the universe.
Superluminous supernovae are the most exotic explosions in the universe. SN 2006gy is one of the most examined and has become captivating to researchers who are attempting to describe how such bright explosions could occur.
But such events have persisted mostly unexplained, with astrophysicists unable to determine the reason for their exceptional light. The light so strongly that they question conventional astrophysical models, which have failed to consider for such a bright star.
The planetary experts made their findings when they stared into the event that the illumination is especially stark in one part of the spectrum. They proposed that vast amounts of iron could account for that particular line.
Anders Jerkstrand from the Department of Astronomy at Stockholm University stated, “It became even more interesting when it suddenly turned out that very high amounts of iron were required to secure the lines, at least a third of the Sun’s mass, which immediately ruled out some old situations and rather exposed a new one.”
The planetary experts recommend that before SN 2006gy became what it is today, there was a second star made up of a white dwarf as massive as Earth, and a large hydrogen-rich huge star that was of the size of our solar system. As the giant star became even more significant, the smaller one was picked up in it and fell in towards the center.
When it got there, the white dwarf popped into a Type Ia supernova that is considered as a standard supernova. It then struck with the envelope encompassing it, forming the massive collision that threw the light streaming beyond the universe.
Now experts believe they have discovered the cause of the blazing illumination coming out of SN 2006gy. And they expect that it could cast light on where other such superluminous supernovae get their energy from.
The original breakthrough came when the experts involved in the study found out that the star achieved its extreme brightness when a typical supernova smashed into a shell of material that enclosed it.
Anders Jerkstrand stated in an interview, “That a Type Ia supernova seems to be following SN 2006gy turns upside down what most planetary experts have thought.”
He further said, “That a white dwarf can be in close orbit with a large hydrogen-rich star, and quickly blast upon falling to the center, gives significant new information for the theory of double star evolution and the requirements necessary for a white dwarf to explode.”
