In June of last year, the new heavenly object similar to the supernova was seen from the Hawaiian ATLAS telescope, but the maximum brightness was much larger and disappeared faster than usual supernova. These parties raised alarm bells for astronomers, so their observations were activated and they concluded It's the birth of a black hole.
Supernova is called "cow" (a special name, but we will see that explanation now), and 45 astronomers think that this is The first time that man dies when a star dies as a black hole. The results of the study were presented this week at the Seattle American Astronomy Association (Washington, United States) at the astrophysical magazine.
There was nothing found from his discovery (good)
We talk about Supernova when the massive star explodes or "kills" This explosion consists of a black hole or a neutron star. We talked about them, for example, when Víctor Buso, an amateur astronomer, by coincidence, found it important to them.
In this case, the behavior called AT2018cow has been seen to be somewhat anomalous, and therefore from the "beef" nickname (cow beef in English). Vaca CGCG 137-068 is a galaxy, with Milky Way "only" 200 million light years away, looking at the Hercules constellation.
Vaca was something special since it was the closest supernova detected, so that astronomers could see it unprecedentedly, as National Geographic explained. We said that the maximum brightness was common, and, in fact, it was registered a brightness than ten times the standard explosion A star (X-ray detection). The brightness that has been shining during the days is usually reduced by shaking the brightness of the supernova normally.
This means that the spillage due to the explosion was much lower than expected (a different composition), the radiation was not expected. They also thought that they were guilty of human error, as director Raffaella Margutti (Northwestern University astrophysicist) says the discovery classifies them as "goals for years".
Raffaella Margutti, the director of the astronomical group, has cataloged the discovery as "the goal of the year's hope"
Thus, they conclude that "beef" is the formation of a black hole or a neutron star. Something so far has not been observed After birth, and a new class of objects within the category of "fast-moving filter filters".
Space and a special cow
It continues investigate about the same cow, how its "central engine" works (that is, the crown, above the observed waste). It is a compact motor that releases high-energy X-rays, which is covered by an amorphous and asymmetrical mass of some types of explosions.
What do you think an anomalous event can help? astronomers understand better the birth of a black hole or a neutron star, we'll see if there is more discovery of cow's hair or this phenomenon is better known.
