Concerning a bounded sequence of finite energy weak solutions to the compressible Navier-Stokes.Poisson system (denoted by CNSP),which converges up to extraction of a subsequence,the limit system may not be the same system.By introducing Young measures as in[6,15],the authors deduce the system(HCNSP)which the limit functions must satisfy.Then they solve this system in a subclass where Young measures are convex combinations of Dirac measures,to give the information on the propagation of density-oscillations.The results for strong solutions to(CNSP)(see Corollary 6.1)are also obtained.
