H, He, C, & N - Equilibrium and Time-Dependent Ion Fractions, Z=2


Get postscript image.



Ion fractions versus gas temperature. Each row displays results for a different element. Left hand panels are for collisional ionization equilibrium (CIE). Right hand panels are for non-equilibrium isochoric and isobaric cooling for Z=2 times solar metallicity gas. Dark curves are for isochoric cooling. Light curves are for isobaric cooling. Panels show H, He, C, and N.
