@article{Shaviv2000TheNO, title={The Nature of the Radiative Hydrodynamic Instabilities in Radiatively Supported Thomson Atmospheres}, author={Nir J. Shaviv}, journal={The Astrophysical Journal}, year={2000}, volume={549}, pages={1093 - 1110} }
Atmospheres having a significant radiative support are shown to be intrinsically unstable at luminosities above a critical fraction Γcrit ≈ 0.5-0.85 of the Eddington limit, with the exact value depending on the boundary conditions. Two different types of absolute radiation-hydrodynamic instabilities of acoustic waves are found to take place even in the electron scattering-dominated limit. Both instabilities grow over dynamical timescales and both operate on nonradial modes. One is stationary…
