GJ 436b (warm Neptune) transmission spectra simulationsSimulated single transit model absorption spectra distinguish betweenequilibrium 30X solar (black), reduced CH4 & H2O (blue, red) or nonequilibriumchemistries where H2O <strong>and</strong> CH4 are absent in favor ofhigher order hydrocarbons HCN, C2H2, <strong>and</strong> other molecules (purple,cyan <strong>and</strong> green curves). 1 transit each: 30 min star + 30 min in-transitintegration time. Noise has been added (Shabram et al. 2011).10
