Professor of Astrophysics at the University of Oxford. I study the atmospheres of other worlds beyond the Solar system.
Happy 30th discovery day 51 Peg b! We're at Observatoire de Haute Provence where it all happened, listening to Michel Mayor & Didier Queloz tell us all about that extraordinary radial velocity discovery with ELODIE on the 1.93m in 1995 and the incredible exoplanet science that followed. What a day!

PSA: ExoMol has a special high res data base, ExoMolHR which now also contains a column with ✨energy uncertainties✨ You can now choose to leave out lines with high uncertainty when making high res model spectra! #AllTheWavelengths @trovemaster.bsky.social

Excellent visit last week to IPAG, Grenoble, talking all things exoplanets+direct imaging; even got a sneak peak in the clean room at new VIPA spectrograph! Big thanks @mickaelbonnefoy.bsky.social & @lucieleboulleux.bsky.social for hosting me, IPAG wins prize for most impressive seminar room door!

Very cool talk from Allona Vazan on a rain of rocks in sub-Neptunes, to explain the radius valley and different interior structure #exoplanets5

Karin Öberg discussing the results of measuring compositions in the outer regions of gas disks. Much, much carbon 👀 #exoplanets5

Björn Benneke proposing that we turn our thinking of sub-Neptune envelopes away from layered atmospheres back to a mixed (miscible) one of H2 with significant H2O or CH4 fraction (e.g. 50/50). Think not oil & water but alcohol & water, much better mixed! #exoplanets5 🪐

It’s #exoplanets5 week! Hannah Wakeford kicking things off with a grand tour of giant exoplanet atmospheres with JWST, so many results from just 2 years of data! Look at this lovely figure she highlighted from Xi Zhang on JWST wavelength coverage of WASP-39 b 🤩 @stellarplanet.bsky.social
