Coupled disc-chemistry and N-body simulations identify three classes of giant-planet atmospheres whose elemental ratios (N/O*, C/O*, C/N*, S/N*) trace gas-dominated, planetesimal-dominated, or drift-enhanced accretion in time-dependent discs.

High-resolution spectroscopy of 51 Peg b confirms atmospheric H2O, constrains high metallicity and solar C/O via Bayesian retrieval, and yields an alternative orbital semi-amplitude of 102.8 km/s with revised mass 0.61 MJup and inclination 49.8 deg.
New ESPRESSO transmission spectroscopy of GJ 436 b shows no detectable atmospheric features from H I, Na I, Fe I or other species, producing upper limits consistent with a featureless optical spectrum.
