The objects which have arrived from other galaxy are found


Scientists of Leiden University have found (Netherlands) near the Milky Way of a star which were probably formed in other galaxy. Article of astronomers is published in the Monthly Notices of the Royal Astronomical Society magazine. Researchers have carried out search of quickly moving objects among seven million stars. For this purpose they have analysed the data on observed provisions, parallax, own movements and beam speeds of stars obtained by the Gaia space telescope. It has allowed to define distance and the general distribution of speeds for all stars. Scientists managed to reveal stars whose speeds were rather big to overcome gravitation of the Milky Way with probability of 50 percent. From this selection researchers have allocated 20 stars which could overcome a galaxy attraction with probability of 80 percent. Calculation of their orbits has shown that among them there are no stars that would have ultrahigh speeds and could arrive from the center of the Milky Way. Astronomers have found seven stars which are running away aside from a galactic disk. Trajectories other 13 objects were away from the galaxy, including orbits of two fastest stars (700 kilometers per second). According to scientists, these stars belong to population of extragalactic stars and could arrive from far galaxies. It is more than important news in Film of Day Telegram-channel. Subscribe!
