The theory of accretion disks are important for many astrophysical phenomena, including Quasars, active galatic nucleic, X-ray binary stars, and young stellar objects. The most important branch of accretion djsk theory is the stability properties of djsks. It is widely considered that the luminosity variations of various astronomical objects are associated with the instability of accretion disk. The viscosity plays an important role in the accretion disk theory, and magnetic field exists commonly in astronomical phenomena. A more realistic analysis of the stabihty of the accretion disk should include both the radjal and azimuthal perturbations because of the strong shear of viscous flow.In this paper, according to the luminosity Variations of Various astronomical objects, we study the radial-azimuthal instability of an isothermal with magnetic field. We find that the radial and azimuthal fields B〓,B〓 are mainly responsible for enhancing the instability of the magneto-acoustic modes and non-axisymmetric modes,and that pulsational oscillations are larger in the radial than in the Z direction. The model may be useful in explaining the periodic light variation of FU orionis and. T Tauri stars.
在许多天体物理现象中,例如活动星系核,X-射线双星和年青的恒星理论中,吸积盘理论起着重要的作用,而吸积盘理论中的一个重要分支是吸积盘的不稳定性理论,普遍认为活动天体的周期,准周期光变现象与吸积盘的不稳定性有关,在吸积盘理论中,粘滞起着重要的作用,而磁场是天体物理中普遍存在的现象,对于几何薄吸积盘不稳定性分析,由于强剪切流的缘故,应该包括径向和环向扰动两个方面,本文结合天体物理中的各种周期,准周期光变现象,研究了含磁场的等温薄吸积盘的径向-环向振荡不稳定性,结果表明:磁场的径向和环向分量对磁声模和非轴对称模的不稳定性的增加起着主要的作用,且径向振荡大于轴向振荡,所得结果有利于解释FU Orionis和T Tauri Stars的周期光变现象。
