INSUBCONTINENT EXCLUSIVE:
Space Telescope has captured the first image of a surviving companion to a supernova, a compelling evidence that some supernovas originate
in double-star systems, the US space agency said.Seventeen years ago, astronomers had witnessed a supernova go off 40 million light-years
companion star was seen in the fading afterglow of that supernova, called SN 2001ig
SN 2001ig is categorised as a Type IIb stripped-envelope supernova
was seen in the fading afterglow of that supernova, called SN 2001ig.According to the study, published in the Astrophysical Journal, the
supernova's companion star was not just an innocent bystander to the explosion
Instead, it was most likely the instigator, as it siphoned off almost all of the hydrogen from the doomed star's stellar envelope, the
companion's thievery created an instability in the primary star, causing it to episodically blow off a cocoon and shells of hydrogen gas
before the catastrophe.Originally, these type of exploding star were thought to come from single stars with very fast winds that pushed off
them for many stripped-envelope supernovas."That was especially bizarre, because astronomers expected that they would be the most massive
interact and transfer gas from one star to the other when their orbits bring them close together," he noted.(This story has not been edited
