Nonlinear dynamics of gravitational instability in complex viscoelastic astrofluids
The nonlinear evolutionary dynamics of gravitational instability in a complex self-gravitating viscoelastic nonthermal polytropic astrofluid is semi-analytically investigated on the Jeansian scales of space and time.The key effects out of fluid buoyancy, thermal fluctuations, and volumetric expansions are concurrently considered and carefully inclu
