Non-equilibrium ionisation and cooling of metal-enriched gas in the presence of a photo-ionisation background
Photo-ionised Non-equilibrium (PINe) and equilibrium (PIE) tables of Z=1 Zsol gas at z=0.5 indexed by temperature. Seven densities (nH = 10-5.0 - 10-2.0 cm-3) are available for eight elements. Temperatures extend from 107 K until the equilibrium temperature where photo-heating balances cooling (T~103.5-104.5 K). Non-equilbrium effects generally do not set in until T<106 K. Included are electron densities, mean molecular weights, cooling times, cooling efficiencies, and ion fractions. Both PINe isochoric and isobaric cases are available, as is the PIE case assuming isochoric cooling. For the isobaric cases, the density listed occurs at T=106 K. Table units are as follows: temperature (T)- Kelvin, hydrogen number density (nh)- cm-3, cooling time (tcool)- yr, cooling efficiencies (Lambdanet)- erg cm3 s-1 where the total cooling rate, Lambdanet, is divided by nH2.
