Bibiana Prinoth | We continue with Sid Gandhi on measuring isotopes in the atmosphere of VHS 1256 b, a directly imaged super-Jupiter (so a big boy close to the brown dwarf regime) with # JWST . Isotopes behave differently, as in are affected differently by photodissociation or partitioning. They detected CO in the atmosphere of this planets, with different C-isotopes in this molecule. The isotope ratios are very well constrained, putting limits on material. # exoplanets5
