Synthetic atmospheric transmission spectra of Ross 176 b. Left: Fiducial models for clear or hazy H/He atmospheres with scaled solar abundances. Right: Model for a steam H2O atmosphere. Simulated measurements

Transit spectra of the best fit non-equilibrium 1D model at resolution 200 (black solid line). This is the approximate best fit on the simulated grid of metallicity, C/O and Kzz.

Graphical Abstract — chemrxiv.org We present a physicochemical framework for understanding the emergence of catalytic logic at the origin of life. In this view, early catalytic systems did not depend
