An article published in the journal “Proceedings of the Japan Academy, Series B, Physical and Biological Sciences” reports a study on the star cataloged as S0-6 which indicates that it formed in another galaxy and only over time reached the center of the Milky Way. Since 2014, a team of researchers led by Shogo Nishiyama of Miyagi University of Education in Japan has been studying various stars that now orbit Sagittarius A*, or simply Sgr A*, the supermassive black hole at the center of the Milky Way.
