We develop and discuss a model formalism to study the properties of mass outflows that are emerged out from a relativistic, magnetized, viscous, advective accretion flow around a rotating black hole. In doing so, we consider the toroidal component as the dominant magnetic fields and synchrotron process is the dominant cooling mechanism inside the accretion disk. With this, we self-consistently solve the coupled accretion-ejection governing equations in the steady state and obtain the shock-induced global inflow-outflow solutions in terms of the inflow parameters, namely plasma-β (=p_gas /p_mag, p_gas and p_mag being gas and magnetic pressures), accretion rates (ṁ) and viscosity (α_B), respectively. Using these solutions, we compute the mass outflow rate (R_ṁ, the ratio of outflow to inflow mass flux) and find that mass loss from the magnetized accretion disk continues to take place for wide range of inflow parameters and black hole spin (a_k). We also observe that R_ṁ strongly depends on plasma-β, ṁ, α_B and a_k , and it increases as the magnetic activity inside the accretion disk is increased. Further, we compute the maximum mass outflow rate (R ^max _ṁ) by freely varying the inflow parameters and find that for magnetic pressure dominated disk, R ^max _ṁ ~ 24% (~ 30%) for a _k=0.0 (0.99). Finally, while discussing the implication of our model formalism, we compute the maximum jet kinetic power using R ^max _ṁ which appears to be in close agreement with the observed jet kinetic power of several black hole sources.

旋转黑洞周围磁化平流吸积盘的质量流出速率研究


我们开发并讨论了一种模型形式主义，用于研究旋转黑洞周围相对论性、磁化、粘性、平流吸积流产生的质量流出的特性。在此过程中，我们将环形分量视为主要磁场，而同步加速器过程是吸积盘内的主要冷却机制。由此，我们自洽地求解稳态下吸积-抛射耦合控制方程，并根据流入参数获得激波引起的全局流入-流出解，即等离子体- β （=p_气体/p_磁力，p_气体和 p_磁力分别为气体压力和磁压力）、吸积速率 (ṁ) 和粘度 (α _B )。使用这些解决方案，我们计算了质量流出率（R _ṁ ，流出与流入质量通量之比），并发现对于大范围的流入参数和黑洞自旋（a _k ）。我们还观察到 R _ṁ强烈依赖于血浆- β 、ṁ、α _B和 a _k ，并且随着吸积盘内部磁活动的增加而增加。此外，我们计算最大质量流出率（右^max _ṁ ) 通过自由改变流入参数，发现对于磁压主导的圆盘，右^最大_ṁ ~ 24% (~ 30%) A _k = 0.0 (0.99)。 最后，在讨论我们的模型形式主义的含义时，我们使用以下方法计算最大喷射动能右^max _ṁ似乎与观测到的几个黑洞源的射流动能非常一致。
