Yo 🪐 spectroscopic #astrodon… how convinced are we that LHS 1140b is a water world?
The paper on arXiv is all “JWST says this be the ultimate wet n’ wild 💦🌊💧” but…
…the spectrum is actually flat.
So… actually nothing has been detected?
The authors say that this rules out a fluffball hot hydrogen atmosphere, as then you WOULD expect something (i.e. methane or carbon dioxide) but does that really constrain it?
