我们使用三维流体动力学模拟表明,一个高度错位的吸积盘周围的一个组成部分的二元系统可以表现出全球Kozai-Lidov周期,其中的磁盘的倾角和偏心率周期性地互换。这对所有尺度上的吸积系统都有重要的影响,例如,行星和卫星在星周和环行星盘中的形成,X射线双星系统的爆发,以及超大质量黑洞的吸积。
We use three-dimensional hydrodynamical simulations to show that a highly misaligned accretion disk around one component of a binary system can exhibit global Kozai–Lidov cycles, where the inclination and eccentricity of the disk are interchanged periodically. This has important implications for accreting systems on all scales, for example, the formation of planets and satellites in circumstellar and circumplanetary disks, outbursts in X-ray binary systems, and accretion onto supermassive black holes.
