Nonlinear stability of a composite wave pattern for non-isentropic compressible Navier-Stokes-Poisson equations with large initial perturbations

Key Points

• Nonlinear stability is observed in a novel composite wave pattern, addressing large initial perturbations.
• The analysis demonstrates how perturbations affect the compressible Navier-Stokes equations under non-isentropic conditions.
• Observational analysis of nonlinear dynamics was used to assess the stability across fluid equations.
• Understanding these wave patterns could enhance predictions in fluid behavior, though more detailed investigations are necessary.
