Bibiana Prinoth | It was not last up… we’ve got one more! Last up, this time for real, we’ve got Thomas Beatty with - spoiler: NOT A FLAT LINE. Thomas starts with the challenges and questions: what do we need to know about an exoplanet to put it in a “HR diagram”. Observations for mass-metallicity plots up to now have been based on the HST WFC3 water band. But wait! We’ve got # JWST now! # ExSSV
