A Conjecture on the Possible Another Supermassive Black Hole in the Bar of Our Milky Way

Abstract

In the bar of our Milky Way, there should be another supermassive black holes B which is with the mass almost 10-2--10-5 the Sgr A* and with a distance10,000--14,500 lightyears from Sgr A*. The bar is formed by the stellar orbiting around both of the black holes. In the Hill radius of B, a lots of stars orbit around B while another lots of stars orbit Sgr A*. It determines that there is a “x-shaped structure” in the bar and the shape of bar appears a peanut. As the orbits of the stars is out of the Hill radius of B, they are repulsed to a distant place by B to form the arms.
