Quantitative estimates of chemical disequilibrium in Titan's atmosphere

Abstract

We apply previously introduced measures of chemical disequilibrium to Cassini mass spectroscopy data on the atmosphere of Titan. In the analysis presented here, we use an improved description, avoiding the meanfield approximation in previous work. The results of the analysis are nearly exactly the same as those found earlier and confirm that, with respect to the measures used, Titan's atmosphere lies between living and many nonliving systems. Some details of the mathematical analysis, which appear to be new, are included.
