Figure 1: Stability curves of the condensates considered in the present work, and evolutionary tracks of the nebula at 12 and 9.8 AU. Abundances of various elements are solar, with CO2:CO:CH4 = 30:10:1 and N2:NH3 = 1 in vapor phase. The condensation curve of CO2 pure condensate (solid line) is shown together with that of thecorresponding clathrate hydrate (dashed line). Species remain in the vapor phase as long as they stay in the domains located abovethe curves of stability. |
