摘要：

This paper is devoted to radial orbit instability in the context of self-gravitating dynamical systems. We present this instability in the new frame of dissipation-induced instability theory. This allows us to obtain a rather simple proof based on energetics arguments and to clarify the associated physical mechanism.
