摘要我们已经开发了一种新的方法,用于后牛顿,高精度的恒星系统包含一个超大质量黑洞(SMBH)的积分,分裂的主要中心力和扰动之间的粒子上的力。我们使用这种方法来执行完全碰撞N体模拟的吸入中等质量黑洞(IMBHs)在银河系的中心。
Abstract We have developed a new method for post-Newtonian, high-precision integration of stellar systems containing a super-massive black hole (SMBH), splitting the forces on a particle between a dominant central force and perturbations. We used this method to perform fully collisional N-body simulations of inspiralling intermediate-mass black holes (IMBHs) in the centre of the Milky Way.
