摘要：

The negative nature of the heat capacity C-V of thermodynamically isolated self-gravitating systems is rediscussed in the framework of a non-extensive kinetic theory. It is found that the dependence of C-V on the non-extensive parameter q gives rise to a negative branch with the critical value corresponding to q = 5/3 (C-V --> infinity). (C) 2003 Elsevier B.V.
