More about the Tolman-Oppenheimer-Volkoff equations for the generalized Chaplygin gas

We investigate the Tolman-Oppenheimer-Volkoff equations for the generalized Chaplygin gas (gCg) with the aim of extending the preivous findings . We investigate both the standard case, where we reproduce some previous results, and the phantom case. In the phantom case we show that even a superluminal group velocity arising for alpha > 1 cannot prevent the divergence of the pressure at a finite radial distance. Finally, we study how a modification of the gCg equation of state, required by causality arguments at densities very close to Lambda, affects the results found so far.
