摘要
在磁场提取黑洞旋转能量的统一模型基础上,给出了MC过程的功率和力矩表达式;并计算了MC过程情况下吸积盘辐射的高发射率指数α。通过研究发现,XMM-Newton天文卫星对Seyfert-1型MCG-6-30-15星系观测到的发射率指数能很好地被有MC过程情况下的薄盘辐射所拟合。
MC power and torque expressions are derived based on a unified model for extracting rotating energy of black holes in a magnetic field.The high emissivity indexes of accretion disk radiation in MC process are calculated.It is found out in the study that the high emissivity produced in MC process is consistent with recent observation of the nearby Seyfert I galaxy MCG-6-30-15.
