Ionization-recombination instability in a photo-ionized nebula
Journal of Physics: Conference Series, 2010 In this work, we consider the thermal (radiation) instability in a weakly ionized plasma with continuous ionization and recombination. The situation can be visualized in the case of envelopes of planetary nebulae, which are envelopes of ionized plasmas surrounding a red giant stars.

Instabilities in the ionization zones around the first stars [PDF]
Astronomy Reports, 2012 We consider the evolution of the ionization zone around Population III stars with $M_*\sim 25-200 M_\odot$ in protogalaxies with $M\sim 10^7 M_\odot$ at redshifts $z = 12$, assuming that the dark matter profile is a modified isothermal sphere. We study the conditions for the growth of instabilities in the ionization zones.

Kelvin–Helmholtz instability in a weakly ionized layer [PDF]
Astrophysics and Space Science, 2007 We study the linear theory of Kelvin-Helmholtz instability in a layer of ions and neutrals with finite thickness. In the short wavelength limit the thickness of the layer has a negligible effect on the growing modes. However, perturbations with wavelength comparable to layer's thickness are significantly affected by the thickness of the layer.

Evolution of the rippled inner-interface-initiated ablative Rayleigh–Taylor instability in laser-ablating high-Z doped targets [PDF]
Matter and Radiation at ExtremesIn the direct drive inertial confinement fusion (ICF) scheme, a rippled interface between the ablator and the deuterium–tritium ice fuel can feed out and form perturbation seeds for the ablative Rayleigh–Taylor instability, with undesirable effects ...
