薄吸积盘中的流体动力学活动

Hydrodynamical activity in thin accretion disks

Oded Regev

摘要:

本文将Kluenniak & Kita(2000)对定态吸积盘流提出的薄吸积盘的渐近处理方法推广到含时问题。轴对称扰动的瞬态增长分析表明,发生在全球磁盘规模。本文还讨论了这一结果对流体动力学薄吸积盘理论的影响以及未来的展望。

英文摘要:

An asymptotic treatment of thin accretion disks, introduced by Kluźniak & Kita (2000) for a steady-state disk flow, is extended to a time-dependent problem. Transient growth of axisymmetric disturbances is analytically shown to occur on the global disk scale. The implications of this result on the theory of hydrodynamical thin accretion disks, as well as future prospects, are discussed.
