摘要

通过数值模拟研究了噪声作用下各向异性自重力n体系统的径向轨道不稳定性。我们发现,根据轨道各向异性的初始值不同,加性或乘性噪声的存在对不稳定性的发生有不同的影响。

Noise, friction and the radial-orbit instability in anisotropic stellar systems: stochastic N–body simulations
Abstract By means of numerical simulations we study the radial-orbit instability in anisotropic self-gravitating N–body systems under the effect of noise. We find that the presence of additive or multiplicative noise has a different effect on the onset of the instability, depending on the initial value of the orbital anisotropy.
