Cornell University Chronicle: ‘Thermometer’ Molecule Confirmed on Exoplanet Wasp-31B news.cornell.edu/stories/2023/0…

(1/n) While I'm not an expert in atmospheric retrievals, I do want to point out something largely overlooked in the discussion so far about the K2-18b transit: a potential stellar flare:

🚨 More JWST observations of TRAPPIST-1 🚨 Thread: (1/n) We observed four flares during transits of TRAPPIST-1 planets and characterized their near-IR spectra out to 3.5 μm for the first time. We used the flare spectra to decontaminate the transits. arxiv.org/abs/2310.03792

Even though this might mean Philip Hopkins gets the prestigious Astro Plot of the Week plot of the week award twice in a row, I have to nominate this accretion disc visualisation — fig. 4 from arxiv.org/abs/2307.01281

My cat submitted my HST proposal for me this year. I’m not kidding. He stepped on the Enter key right as I was getting ready to click it. Hopefully he’s my good luck charm.

I recently had the pleasure to lead the analysis of a new survey for young brown dwarfs and free-floating planets with JWST. Our observations included this spectacular image of the young star-forming cluster NGC1333, highlighted by European Space Agency/ESA Webb Telescope. What are the key results?🧵👇
