摘要:

我们考虑环形吸积盘(RADs),代表模型的聚集体的同向和反向旋转的环轨道中心克尔超大质量黑洞(SMBH)。本文讨论了由多方状态方程控制的含有环形磁场的双圆环系统。我们发现RAD主导函数描述RAD内部结构和控制的轨道环形结构的分布和出现的(流体力学)不稳定性的磁盘。我们首先在纯流体动力学模型中进行分析,考虑单种完美流体环,然后考虑环形磁场的贡献。

英文摘要:

We consider ringed accretion disks (RADs), representing models of aggregates of corotating and counterrotating toroids orbiting a central Kerr super-massive black hole (SMBH). We comment on system of two-tori governed by the polytropic equation of state and including a toroidal magnetic field. We found the RADs leading function describing the RAD inner structure and governing the distribution of orbiting toroidal structures and the emergence of the (hydro-mechanical) instabilities in the disk. We perform this analysis first in pure hydrodynamical models by considering one-specie perfect fluid toroids and then by considering the contribution of toroidal magnetic field.
