摘要：
We explore the Core Fundamental Plane (CFP) for a sample of 40 low redshift 132 radio galaxies that have been imaged at high resolution by HST. We find that the CFP of radio galaxies is indistinguishable from the one of non radio elliptical galaxies. It is also indistinguishable from the Fundamental Plane (FP), of normal and radio galaxies. Similarly to what found for early type non radio galaxies these results suggest that the cores are in dynamical equilibrium supported by random motions, and that mass-to-light ratio in the core varies smoothly.
