Claire Moutou, another exoplanet specialist at the Laboratory of Astrophysicsof Marseille in France, agreed. “I find the analysis/conclusions of the paper reasonable, as far as the amount of oxygen available to lie in H2O molecules is concerned. The interpretation of the origin of this water content is more speculative.”
