英文摘要: We study the self-gravitating stars with a linear equation of state, P = a rho, in AdS space, where a is a constant parameter. There exists a critical dimension, beyond which the stars are always stable with any central energy density; below which there exists a maximal mass configuration for a certain central energy density and when the central energy density continues to increase, the configuration becomes unstable. We find that the critical dimension depends on the parameter a, it runs from d = 11.1429 to 10.1291 as a varies from a = 0 to 1. The lowest integer dimension for a dynamically stable self-gravitating configuration should be d = 1.2 for any a is an element of [0, 1] rather than d = 11, the latter is the case of self-gravitating radiation configurations in AdS space.
