磁重联在喷流/吸积盘系统中的作用

The role of magnetic reconnection on jet/accretion disk systems

E. M. de Gouveia Dal Pino, P. P. Piovezan, L. H. S. Kadowaki

摘要:

早先有人提出,在微类星体中观测到的相对论性抛射可能是由内盘冕区剧烈的磁重联事件产生的。在这里,我们重新审视这个模型,它采用了标准的吸积盘描述和快速磁重联理论,并讨论了磁重联和相关的加热和粒子加速在不同的喷流/盘吸积系统,即年轻的恒星物体(YSO),微类星体,和活动星系核(AGN)的作用。

英文摘要:

It was proposed earlier that the relativistic ejections observed in microquasars could be produced by violent magnetic reconnection episodes at the inner disk coronal region. Here we revisit this model, which employs a standard accretion disk description and fast magnetic reconnection theory, and discuss the role of magnetic reconnection and associated heating and particle acceleration in different jet/disk accretion systems, namely young stellar objects (YSOs), microquasars, and active galactic nuclei (AGNs).
