Earth-sized or super-Earth planets forming far enough from their stars for ices to condense may consist of large amounts of volatiles, leading to thick ice layers on top if they differentiate.
“Earth-sized or super-Earth planets forming far enough from their stars for ices to condense (see Section 3.1.3) may consist of large amounts of volatiles, leading to thick ice layers on top of these planets if they differentiate (Léger et al., 2004).”

“…photochem build-up of O2 (Selsis et al., 2002): (i) CO2-rich atmospheres:PCO2 > 50 mbar for dry atmospheres,PCO2 > 0.5 bar for wet atmospheres, and (ii) water-rich atmospheres loosing hydrogen to space after H2O photolysis (for instance during a runaway greenhouse effect as describ Kasting, 1988).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
