We continue with Jackie Faherty on #methane #emission in a cold #exoworld with #JWST.

We start with a controversial topic: what is a planet? 🥹 Jackie works with #brown #dwarfs, and she asks us to pretend we talk about exoplanets 🤓

T and Y dwarfs are colder objects, basically Jupiters.

Jackie shows us a wonderful temperature sequence - or is it? Look at the carbon chaos! There is no sequence. Welcome to the BD mess ✨ #ExSSV
