A new star of the main sequence was discovered the other day. researchers. This object is considered the fastest in this varieties. A star rushing in outer space with a huge at a speed of 1700 km / s, moving away from the center of the galaxy. Informs Science Alert.
Scientists are convinced that object S5-HVS1 was literally thrown out of the center of the Milky Way due to the supermassive black hole of Sagittarius A. According to scientists, this star is about 500 million years old with life expectancy of 1 billion years. Object refers to spectral class A, whose temperature reaches 7500-10000 Kelvin. The mass of this object is 2.35 times that of the Sun.
According to scientists, such hyperspeed stars of the main sequences are not so common. Basically they belong to the spectral classes O (blue) and B (white-blue color) with a lifespan of several tens million years. The most common high-speed neutron stellar objects that remained after the flare supernova.
In 2018, scientists were able to detect high-speed whites. dwarfs flying 2,200 kilometers in one second.
As for white dwarfs and neutron stars, their high the speed depends on the asymmetric explosion – at the moment of transformation stars in a supernova of type Ia or type II.
The current position of the object S5-HVS1, which is removed by 29 thousand light years from Earth, as well as its speed show that its the departure from the galaxy has been going on for about 4.8 million years.
