Proud to announce that my first PhD paper has now been accepted and is live on arXiv!! arxiv.org/abs/2603.24662 In this paper I provide the first analyses of JWST spectra of a sample of young, co-eval L dwarfs, focusing on the silicate absorption and whether there are any equator-to-pole variations.

Clouds with a silicate lining: Using JWST spectra to probe atmospheric diversity in young AB Dor L dwarfs
We present the first full JWST NIRSpec Prism and MIRI LRS 0.6 - 14 $μ$m (R ~ 100) spectra and analysis of five ~ 133 Myr L dwarf members of the AB Doradus moving group and one probable $\sim 500$ Myr ...

TWO recently accepted papers on arxiv today from our group, led by PhD students @maddielam.bsky.social and @astrotoole.bsky.social. If you like brown dwarfs, variability, clouds, aurorae and/or magnetic spots there is something here for you! 👀 arxiv.org/abs/2603.24662 arxiv.org/abs/2603.24663

🔭 It's paper day! Today I'm sharing the latest in a series of papers looking at the weather on other worlds, in this case bringing you the weather report from a nearby T-dwarf, SIMP-0136. 🪐 🧵 to follow...

A very hungry planet! 🪐 What appears to be a ripple in space is actually a newborn planet, eating its way through its dusty cradle around a younger version of our Sun 🌞 Read more: www.eso.org/public/images/potw2534a 🔭 🧪 #exoplanets 📷 ESO/R. van Capelleveen et al.
A white protoplanetary disc at the centre of the picture takes up most of the frame. The elliptical cloud of dust and gas consists of some gaps creating a ring-like structure to the cloud. In one of the larger gaps/rings a little dot (a planet) is visible.

Attended my first ever conference last month at #EASCork! Super inspiring to hear about what’s going on in exoplanets and brown dwarfs!
