which type of star turns into a black hole

It is definitely not the archetypal image we have of a black hole that consumes everything in sight. It barely interacts with the environment around it and does not put out any X-ray energy usually associated with black holes. Why wouldn’t the black hole simply swallow up the star? Well, this particular black hole is almost inert, in a sense. On first glance, the idea of a black hole next to a totally fine “living” star seems almost like an oxymoron. So what makes a black hole dormant? This is something scientists would love to understand better. Tatooine-Like Star Systems Could Be Home to Aliens Scientists believe that the dormant black hole is 9 times the mass of our sun at least, so it’s not all that much different in mass than the star but the star is 200,000 times larger in volume than the black hole. VFTS 243 was observed first as a single star 25 times the mass of the sun, then as a single star that had a companion. The research appears now in Nature Astronomy. It was discovered at the European Southern Observatory, in Chile, by the aptly named Very Large Telescope. That’s what researchers believe happened to the binary star VFTS 243 in the nearby Large Magellanic Cloud. Or both stars can stay together until one simply reaches the end of its long life. One star can basically “eject” the other, which is what some scientists believe could have happened to a theoretical sun-paired star tantalizingly named Nemesis. When they grow too close, one of two very different things can happen. Young stars start farther apart but many are part of pairs, and older stars have moved closer together over billions of years. It follows logically that they’d snag each other and start the long, slow process of orbiting closer and closer together-like the quarter you drop into a spiral wishing well. Because of their powerful gravities, stars have huge fields of influence on the space around them. But this idea also makes intuitive sense.

They may be up to 10,000 or more light years apart, which can make them challenging to pick out. It turns out that scientists believe most stars are part of binary star systems, meaning two stars that are gravitationally stuck together at some distance and end up orbiting each other. This is a special category of black hole that exists when one star in a binary pair dies before the other, leaving a black hole that can’t escape the other’s gravity but does not suck up matter or emit its own powerful energy as expected-hence “dormant.” To understand, we need to get twisted up in the spinning distance between binary stars. In new research, scientists bring forward one of the first known examples of a dormant black hole. Pairs of black holes, and how they could form, are key to understanding gravitational waves.The pair of stars likely swirled together for billions of years before one went dark.Scientists have found their first dormant black hole outside the Milky Way.
