Hydrodynamics, Instabilities, Ism: Evolution
Scientific paper
Hydrodynamic instabilities play an important role in determining the morphology and evolution of astronomical entities. Any interface of discontinuous density is subject to instabilities, including Rayleigh-Taylor, Kelvin-Helmholtz, and a recently discovered instability driven by self-gravity. In an ongoing computational study, we seek to validate the linear theory developed for the self-gravity-driven interfacial instability and examine its non-linear behaviour. Here, we present the results from hydrodynamic simulations designed to expand the parameter space and investigate the effects of perturbation strength, Atwood number and compressibility.
