摘要：
The compressible Navier-Stokes-Poisson equations driven by a time-periodic external force are considered in this paper. The system takes into account the effect of self-gravitation. We establish the existence of weak time-periodic solutions on condition that the adiabatic constant satisfies gamma > 5/3.
