A Full Loss Cone For Triaxial Galaxies

摘要: Stars and compact objects that plunge toward a black hole are either 1) captured, emitting gravitational waves as the orbit decays, 2) tidally disrupted, leaving disc of baryonic material, 3) scattered to large radius, where they may thereafter avoid encounters with or 4) swallowed whole, contributing growth. These processes occur on dynamical time, which implies for static spherically symmetric stellar system, loss cone is quickly emptied. However, most elliptical galaxies spiral bulges thought be triaxial in shape. The centrophilic orbits comprising backbone galaxy have been suggested one way keep around supermassive filled stars, remnants, intermediate mass holes. We investigate evolution population model high resolution N-body simulations. find enough regular flow through angular momentum space maintain full Hubble time. This increases astrophysical capture rate by several orders magnitude. In Milky Way, example, we white dwarf can $10^{-5}$ per year, 100 times larger than previous estimates based spherical models bulge.
