Washington (Reuters) -Tasronomers noticed the results of an unfortunate star who chose the wrong dance partner. They recorded what a new kind of Supernova looks like because there are well -known star explosions that occurred when a massive star tried to swallow a black hole with which she was engaged in a long pas de deux.
The star, which was at least 10 times more massive as our sun, and the black hole, which had a similar mass, was gravitationally bound with each other called binary system. However, when the distance gradually narrowed them, the huge Black Hole gravitational attraction seemed to distorted the star – stretching it from the spherical shape – and, before exploding, puffed the material.
“We caught a huge star locked in a deadly tango with a black hole,” said Alexander Alexander Gagliano from the US National Science Foundation AI and the Massachusetts Institute of Technology, published this week in this week’s astrophysical magazine.
“After a year of Mass’s death in a spiral with a black hole, the mass star met with her finale blasting. She spent more energy in a second than it was the sun throughout her life,” Gagliano added.
The explosion took place about 700 million light -years from the ground. The year of light is a distance of distance per year, 5.9 trillion miles (9.5 trillion km).
“The gravitational traction of two objects was actually similar because we think they had similar masses. But the star was much larger, so it covered the black hole because the black hole pulled out the material. The star was large but purulent and the black hole was small but powerful.
Investigators are not sure about the exact mechanism that caused a supernov.
“It is unclear whether the distortion causes instability that causes the star to collapse and then the rest of the star material is quickly eaten by the black hole, or the black hole completely pulls out the star until it remains supernova,” said Ashley Villar, a Harvard University astrophysicist.
“The star was drawn in difficult ways and shocked by a black hole,” Villas added.
The binary system began with two massive stars that hurt each other as space companions. But one of the two stars reached the end of a natural life cycle and exploded in supernova, and its core collapsed to form a black hole, an extremely dense object that is so strong that it is not even light to escape.
“This event reveals that some supernovios can be caused by Black Hole companions that give us new insights on how some stars end their lives,” said Villar.
Stars, which are at least eight times more massive than the sun, seem to end supernova to their lives. Those with a mass of at least 20 times higher than the sun will form a black hole after the explosion.
The artificial intelligence algorithm to scan unusual space explosions in real -time, first determined the beginning of the explosion, providing a warning that allowed astronomers to take further observations immediately. It was completed before the explosion and was noticed by numerous ground and space telescopes.
“Our AI algorithm allowed us to carry out a comprehensive surveillance of the observation enough early enough to see the whole picture for the first time,” Gagliano said.
The observations of a star dating from four years before Supernova revealed the pronounced emissions that astronomers thought were caused when the black hole was pumped by the star. For example, the star’s outer layer of hydrogen seems to have been torn out, uncovering the helium layer below.
Investigators noticed the pronounced emissions of the explosion when the black hole consumed the remaining star garbage. Eventually the black hole became more massive and powerful.
Systems that group two or more companions are quite common. Some of these repeat has a black hole as one of the companions.
“Our performance is that the fates of the stars are extremely influenced by their companions or companions in life. This event gives us an interesting window to how dramatically black holes can affect the death of mass stars,” Gagliano said.
