10.7. Absorption columns with bright X-ray sources near the galactic center: — mass estimation in the Galactic center region
Published online by Cambridge University Press: 25 May 2016
Abstract
We report the column density distribution to the Galactic Center region using the X-ray binary observations with the X-ray satellite ASCA, and demonstrate a new method of the total mass determination near the Galactic Center. The column densities are given by a simple form as a function of the angular distance from the Galactic Plane. Assuming a disklike mass distribution of 500 pc radius, we estimate the total mass to be ~ 6 × 107M⊙.
