Our new paper on COCONUTS-2b is out. ui.adsabs.harvard.edu/abs/2024arXiv2
 Yes, that planetary-mass companion near the T/Y transition. We got a new NIR Gemini spectrum (R~1000) and compared it + MIR photometry against basically ALL the model grids for T/Y dwarfs, including your favorites.

Main takeaways: đŸ„„ Disequilibrium chemistry, along with diabatic thermal structure and/or clouds in COCONUTS-2b's atmosphere đŸ„„ Sub-/near-solar [M/H] & C/O vs. solar metallicity of its host đŸ„„ Discussions of major offsets between observed spectra vs. models in the T/Y regime
