Global Solutions to the One-Dimensional Compressible Navier--Stokes--Poisson Equations with Large Data

In this paper, we study the global solutions with large data away from vacuum to the Cauchy problem of the one-dimensional compressible Navier--Stokes--Poisson system with density-dependent viscosity coefficient and density- and temperature-dependent heat-conductivity coefficient. The proof is based on some detailed analysis on the bounds on the density and temperature functions.
