边缘无碰撞吸积盘日冕中的重联
Reconnection in Marginally Collisionless Accretion Disk Coronae
摘要：
我们指出，一个传统的建设放在观测吸积黑洞，其中它们的非热X射线光谱产生的逆康普顿在日冕等离子体，表明等离子体是轻微碰撞。等离子体物理的最新发展表明，快速重联只发生在无碰撞等离子体中。正如最近对太阳日冕的研究所提出的，这种边缘状态可能是能量平衡和快速磁重联的要求相结合的结果。
英文摘要：
We point out that a conventional construction placed upon observations of accreting black holes, in which their nonthermal X-ray spectra are produced by inverse comptonization in a coronal plasma, suggests that the plasma is marginally collisionless. Recent developments in plasma physics indicate that fast reconnection takes place only in collisionless plasmas. As has recently been suggested for the Sun's corona, such marginal states may result from a combination of energy balance and the requirements of fast magnetic reconnection.
