Richtmyer-Meshkov mixing layer growth from localized perturbations
Britton J. Olson, Robin Williams
We study the growth of Richtmyer-Meshkov mixing layers from an initial surface with spatially localized perturbations. We use two symmetric forms of the initial patch, which allow…
The classical D-type expansion of spherical H II regions
Robin J. R. Williams, Thomas G. Bisbas, Thomas J. Haworth +1
Recent numerical and analytic work has highlighted some shortcomings in our understanding of the dynamics of H II region expansion, especially at late times, when the H II region a…
Ultraviolet emission lines of Si II in cool star and solar spectra
Sibasish Laha, Francis P. Keenan, Gary J. ferland +6
Recent atomic physics calculations for Si II are employed within the Cloudy modelling code to analyse Hubble Space Telescope (HST) STIS ultraviolet spectra of three cool stars, Bet…
Self-Consistent Dynamic Models of Steady Ionization Fronts I. Weak-D and Weak-R Fronts
William J. Henney, S. Jane Arthur, Robin J. R. Williams +1
We present a method for including steady-state gas flows in the plasma physics code Cloudy, which was previously restricted to modeling static configurations. The numerical algorit…
