An Oxidation Gradient Straddling the Small Planet Radius Valley

An Oxidation Gradient Straddling the Small Planet Radius Valley

We present a population-level view of volatile gas species (H _2 , He, H _2 O, O _2 , CO, CO _2 , CH _4 ) distribution during the sub-Neptune to rocky planet transition, revealing in detail the dynamic nature of small planet atmospheric compositions. Our novel model couples the atmospheric escape mo...
