A Black Hole Banished In A Neutron Star. It Happened After 10 Days


Two years later LIGO detected collision of two neutron stars – burnt remnants of stars larger than the sun but not large enough to turn into black holes. Such collisions make up most of the gold and silver in the universe.

With the help of VIRGO, a similar but smaller European gravitational wave observatory located in Italy, astronomers were able to locate the sky where the explosion occurred, and a series of telescopes were then able to detect particles of light from the radio waves. to the X-rays coming out of that fireball.

Astronomers have long hoped to find a neutron star orbiting a black hole, but in nearly half a century of research into our Milky Way galaxy they never found one. Dr. “So we actually ran into this mystery question,” Brady said. “Why haven’t we seen a neutron star-black hole system?”

In 2019, it looked like two gravitational wave detections had finally packed this elusive astronomical quarry. However, one of them was not reviewed in April 2019. It could be what they hoped for – the rumble of a black hole-neutron wave collision – or it could be random, meaningless fluctuations in imperfect data.

Dr. “We think it’s unlikely that it’s really an astrophysical signal,” Brady said. “So it looks like it’s one of those things that could happen out there, but right now we don’t have enough evidence to say it is.”

The second detection on August 14, 2019 remains surprising. The larger object in the collision was definitely a black hole. The smallest was 2.6 times the mass of the sun. It’s larger than any neutron star ever detected and smaller than any black hole ever detected. Astronomers aren’t sure if it’s a neutron star or a black hole.

The new gravitational wave observations finally prove that these couples undoubtedly exist, albeit very far from the Milky Way. The first detection of a neutron star merging with a black hole occurred on January 5, 2020. The facility in Hanford, Wash. was temporarily down, so the signal was detected in Livingston, La. VIRGO detector in Italy received a weak signal that provides authentication.
