A Super-Giant Black Hole Ejects Stars From Our Galaxy

Hello everyone, Today I will talk about A supermassive or Super-giant black Hole that Ejects Stars From Our Galaxy. Before start a today's' topic lets check some of this fundamental Issue about black hole.




    What is Supermassive Black Hole:

    The black hole which is a million and a billion times bigger than a stellar Black Holes. The Medium size of black hole is stellar. A supper massive Black Holes exist in the center of the largest Galaxy including our own Milky Way galaxy.

    How Do Supermassive Black Holes Form?

    Scientists believe that supermassive Black holes Formed when the galaxy created.

    Will the Sun Ever Turn Into a Black Hole?

    The sun doesn't have enough gravitational force collapse into a black Holes. When the sun is in his end of the life after in billions of years, it will become a red giant star. Then when it lost all of his energy, the sun will become a cooling white dwarf star.


    A Super-Giant Black Hole Ejects Stars From Our Galaxy









    If the stars were to arrange sprint races in the sky, then as five dash H VS one would surely leave its rivals far behind like the invincible champion Usain Bolt, nicknamed lightning bolt, the runner who has been clocked at a maximum speed of 27.79 miles (44.72 kilometers) (44.72 kilometers) or 44.72 kilometers an hour is listed in the Guinness Book of World Records.

    Only unlike the track and field athlete, a hypervelocity star awaits not honor and glory but loneliness and eternal wanderings in a foreign land. In fact, of course in space, there are no sports competitions, but about the fate of the would-be fastest star in our galaxy.

    Everything is serious. At least such conclusions are made by scientists. According to the results of recent studies.

    A group of astronomers led Sergey koposov off of Carnegie Mellon University's make Williams center for cosmology discovered s5 dash H vs one by accident with the help of the Anglo Australian telescope or at a 12.8 foot or 3.9 meters telescope and the guy at space observatory of the European Space Agency, they conducted spectroscopic imaging of the stellar streams in the Southern Hemisphere.

    At the same time, scientists were attempting to find interesting space objects in the Milky Way when they suddenly noticed a star moving in the group constellation at a speed of about 3.72 million miles for 6 million kilometers per hour. That is 10 times faster than normal. Now, s five dash H v s one is located just 1000 light-years from Earth.

    This is very close considering the scale of a galaxy researcher was able to trace the path of s five dash H vs one back in time. It turned out that the star was flying from the center of the Milky Way where Sagittarius A star hides a black hole.

    More than 30 years ago, jack Hill suggested that black holes could eject a star from binary systems with an incredibly powerful force.

    The same scenario developed in the case of s five dash H s v one, which was able to escape from gravitational monster Sagittarius A star this black hole is located in the center of our galaxy at a distance of 26,000 light-years from Earth, its mass exceeds our sons by 4 million times like other black holes.

    Sagittarius A star attracts all known objects, including those that move at the speed of light, the light quanta can't escape this region.

    However, with the hypervelocity star, it probably works out a little differently. Under the influence of the gravitational force of a black hole, the binary system of stars, the Kade, the black hole swallowed one of the stars, but that star forced s5 HSV one away from itself.

    Now, this star moves at a speed of almost 1090 miles or 1755 kilometers per second. Scientists suggest that this happened about 5 million years ago.

    At that time, our distant ancestors had just learned to walk upright. Since then, the star has been racing so fast for space that it's likely to leave our galaxy entirely at some point in the future.

    However, as it turns out, s5 dash H vs. One is not the only star to roam the universe alone.


    Astronomers managed to find other hypervelocity rogue stars, finding them is no easy task either. Closer to the center of the Milky Way, a huge number of various luminaries are forced to move, as they say, shoulder to shoulder. To single out a few particular stars from billions is like looking for the proverbial needle in a haystack by astronomers Keith Hawkins, who is an astronomy student at Ohio University and Adam Krauss and astronomer at the University of Hawaii using the five-meter telescope at the Palomar Observatory in California were first able to view 130 stars that were not far from Sagittarius A star. Then among them, they identified six sprinters with a mass very similar to that of our son.

    They all travel at extreme speeds of up to 2 million miles Score 3.2 million kilometers per hour. According to the astronomers, this six stars most likely were also thrown out of the center of the Milky Way.

    Researchers are using these stars to lift the veil on their birth in the dark depths of the Milky Way, a large amount of interstellar dust is concentrated in the galactic center, and the light coming from its depth is diminished by 30 magnitudes.

    That's about 10 to the 12 power times. Therefore, the center is invisible not only to the naked eye but even with the help of very powerful telescopes.

    The identification of such celestial bodies will also help scientists more accurately estimate the size of the supermassive black hole hiding in the center of our galaxy.

    However, hypervelocity stars are not always able to get the Researcher's information about Sagittarius A star. Some of these travelers most likely didn't even come close to the Galactic monster. So astronomers traced the history of the trajectory of the huge distance Star Lemnos dash H vs one, which is located at a distance of about 42,000 light-years from Earth.

    They found that this giant started to accelerate from a location in one of the small spiral arms of the galaxy is not from the center of it. It turned out that Sagittarius A star couldn't be blamed for forcing this star away.

    So what then accelerated the star to such inconceivable speed. At first, the scientists decided that this was the result of a collision of Lemnos h vs one with several massive stars, but the path of this sprinter supposedly original mates in the spiral arm of the Milky Way known as the normal arm.

    So according to astronomers, a black hole could also be hiding there. Not a giant one, but one of medium size, it's likely that a similar space object is guilty of expelling Lambos dash HBS one from its place of origin in the spiral arm of the Milky Way.

    Also, another 20 hypervelocity stars have been discovered that arrange super races across the galaxy. They belong to the orange and yellow dwarfs, that they're similar to our son, presumably, they don't originate from the galactic nucleus or GM scientists have made a similar conclusion based on a study of the composition of these bodies.

    It turned out to be the same as that of other stars in the disk of the galaxy is different from the composition of those born in the center of the middle The way it turns out that they are dispersed not by the black hole, Sagittarius A star, but by something else, what exactly is still unknown.

    Furthermore, the conclusions about the extreme speed of old 20 stars need further investigation to know what discoveries scientists will make. Perhaps it'll turn out that these 20 stars came to us from some completely different location entirely.

    Researchers at the University of Cambridge using a computer simulation have hypothesized that hypervelocity stars often enter our galaxy from the Large Magellanic Cloud or LMC. their origin is explained by the decay of binary systems.

    The closer to companion stars are in binary stellar systems, the faster they rotate relative to each other. If at some moment, one star explodes, like a supernova, the Remaining one flies away at the speed with which it rotated.


    Because the mass of the LMC is only about 10% of the mass of our galaxy, the gravitational force there is much weaker, a hypervelocity star can easily overcome its attraction and escape.

    To confirm their theory, the scientists model the life cycle of stars in the LMC over the past couple of billion years and revealed the effects of the birth of hypervelocity stars. Next, their path to our galaxy was calculated.

    When the calculation results were compared with observations, then everything came together. The actual locations of the hypervelocity stars exactly matched the place is shown by the simulation about 10,000.

    Such fast stars according to computer simulation will eventually make it to our galaxy, but this is only a small fraction of those that were ejected from the LMC transition from one galaxy to another takes millions and even billions of years.

    During this time, most stars are likely to die turning into black holes or neutron stars. And if the computer simulation is correct, not only many hypervelocity stars but also neutron stars, as well as black holes are rushing towards our galaxy from the Large Magellanic Cloud, scientists hope in the next decade to conduct additional research on this and other theories of the appearance of the fastest stars in the Milky Way.

    And with this task, the James Webb Space Telescope or JWs T is sure to help. It should become an official replacement for the Hubble observatory which has been in orbit for almost three decades.

    And who knows, maybe new knowledge about the star marathon will tell us how to accelerate spacecraft to achieve Flight around the galaxy in the future.

    Do you think that new knowledge of hypervelocity stars will bring us practical benefits?
