标题： Global dynamics of advection-dominated accretion flows with magnetically driven outflow

摘要： 我们研究了以吸积盘为主的磁场驱动外流的全局动力学。 吸积流中的一部分气体被加速到外流中，这导致黑洞附近的吸积流质量吸积率下降。 我们发现，在吸积盘不稳定性解（ADIOS）假设的幂律依赖关系 m_dot r^s 的外区，ADAF 的 r 依赖的质量吸积率接近于一个幂律形式，而在 ADAF 的内区则显著偏离这种幂律依赖的质量吸积率。 研究表明，在存在外流的情况下，ADAF 的结构发生了显著变化。 在有外流的情况下，ADAF 中离子和电子的温度降低，因为部分来自 ADAF 的引力能被用来加速外流。 显示英文摘要

摘要： We study the global dynamics of advection-dominated accretion flows (ADAFs) with magnetically driven outflows. A fraction of gases in the accretion flow is accelerated into the outflows, which leads to decreasing of the mass accretion rate in the accretion flow towards the black hole. We find that the r-dependent mass accretion rate is close to a power-law one, m_dot r^s, as assumed in the advection-dominated inflow-outflow solution (ADIOS), in the outer region of the ADAF, while it deviates significantly from the power-law r-dependent accretion rate in the inner region of the ADAF. It is found that the structure of the ADAF is significantly changed in the presence of the outflows. The temperatures of the ions and electrons in the ADAF decreases in the presence of outflows, as a fraction of gravitational power released in the ADAF is tapped to accelerate the outflows.
