About 780 million years ago, at 780 million light-years away, there was a weird stellar object which was destroyed by a black hole. This black hole was 23 times more massive than the sun. The mysterious object cannot be placed in a category since it’s bigger than any known star but less massive than any black hole that was ever found.
The collapsed stars, which are called neutron stars, are 2.14 times the mass of the sun. But black holes are not smaller than five solar masses.
What does this mass gap mean?
This mass gap occurs due to the neutron stars and black holes representing possible outcomes for dying high-mass stars. The death of such a thing means amazing supernovae that go through a transformation of the star’s remaining hyper-dense core into a neutron star or a black hole. So a more massive core will turn the core into a black hole, and a less massive core will turn it into a neutron star. This means that there must be some kind of the point, a number, above which a black hole is preordained and below which a neutron star forms.
What scientists have to say about this? “It breaks the record.”
According to Vicky Kalogera, an astrophysicist at Northwestern University, “We’ve been waiting decades to solve this mystery. We don’t know if this object is the heaviest known neutron star or the lightest known black hole, but either way, it breaks a record. If it’s a neutron star, it’s an exciting neutron star. If it’s a black hole, it’s an exciting black hole.”
