Self-oxidation of the Atmospheres of Rocky Planets with Implications for the Origin of Life

by Keith Cowing

Rocky planets may acquire a primordial atmosphere by outgassing of volatiles from their magma ocean. The distribution of O between H2O, CO and CO2 in chemical equilibrium subsequently changes significantly […]
