TRAPPIST-1 g magma ocean evolution with different relative accuracies ϵ in the integration during runtime for additional Co₂, the mass of which is scaled by a factor of 1 with the initial H₂O masses in the system (red: ϵ = 10^–1, green: ϵ = 10^–2, purple: ϵ = 10^–3). Top panels show surface temperatures, middle panels show volatile partial pressures (solid: H₂O, dashed: CO₂ dotted: O₂), bottom panels show net flux for initial water masses of 1 TO, 5 TO, and 100 TO from left to right.
