TABLE 8: EQUILIBRIUM CONDENSATION TEMPERATURES FOR A SOLAR-SYSTEM COMPOSITION GAS see K. Lodders 2003, ApJ 591, 1220-1247 for description NOTE: At 10-4 bar total pressure. Solar system abundances from Table 2. a 22.75% of oxygen is condensed into rock before water ice condensation. b Major condensed reservoir of element. c Condensation temperature of pure iron metal. d Modeling assumes solution of FeSe0.96 for which reliable thermodynamic properties exist, instead of FeSe.
