The National Astronomical Observatory of the Chinese Academy of Sciences found that the recovery of the present galaxy’s rotation and acceleration of stars
According to CCTV news client news, the reporter learned from the National Astronomical Observatories of the Chinese Academy of Sciences that the research team found stars based on data from the Guo Shoujing telescope, a major national scientific and technological infrastructure, and found stars that could replace the acceleration of the current galaxy’s rotation speed.This result was published in the international academic journal Astrophysical Letters recently.Chinese astronomers have discovered that the current galaxy’s rotation accelerates stars, and its rotation speed is about 540 seconds, which is about one hundred seconds faster than the current star with the second fastest rotation speed in the Milky Way.The scientific research team analyzed the spectrum of the star in the Milky Way with a faster rotation speed and found that it was a very hot massive star.Due to the ultra-fast rotation speed, the star becomes flattened, which leads to its low equatorial temperature and low gravitation, and the light emitted is relatively dim; while the temperature of the two poles is high and the gravitation is large, the light emitted is relatively bright.Further research revealed that this star is located on the outer spiral arm of the Milky Way, about 30,000 light-years from the Sun.The star is leaving its current position at a speed of about 120 millimeters per second, suggesting that the star may have originated from the binary star effect. The expansion of the star in the late stage of the host star caused the star to accumulate the host star’s material, which accelerated its rotation.In the end, as the main star exploded as a supernova, the star was thrown out and became a star whose rotation speed accelerated in the Milky Way.Editor Yang Li Source: CCTV News Client
