Astrophysics from the University of Cambridge (UK) showed that dwarf elliptical galaxy in Sagittarius deforms the disk of the Milky Way. The study is published in the journal Monthly Notices of the Royal Astronomical Society, is available at arXiv.org briefly about it informs edition of New Scientist.
Scientists have analyzed the movement of the stars in the star system and concluded that the dwarf elliptical galaxy in Sagittarius was originally mass of the Sun 60 billion times. By now it has become easier to hundred times. Thus, scientists in the observations confirmed the theoretical conclusions colleagues linking weight loss dwarf elliptical galaxy in Sagittarius with the Milky Way's disk deformation.
Dwarf elliptical galaxy in Sagittarius discovered in 1994. It is at a distance of 80 thousand light-years from Earth. Milky Way as a result of tidal interactions tearing it to pieces, and the dwarf galaxy distorts his drive - some parts of it as a result of this are located above and below the galactic plane.
Transformation of the Milky Way for the first time discovered in 1956 in the course of radio observations of its external disk. In 2011, fellow authors of a new study have suggested that dwarf elliptical galaxy in Sagittarius influences the formation of the spiral structure of the Galaxy.
