I am delighted to share that my first paper has now been accepted for publication in Astronomy and Astrophysics and is now on the arXiv!! arxiv.org/abs/2603.24663 In this paper I disentangle the drivers of variability in three early L-dwarfs using HST/WFC3. More info below 🧵!!

Disentangling auroral, cloud and magnetic spot driven variability in three early L-dwarfs with HST/WFC3

Variability monitoring provides an unparalleled insight into the atmospheric processes of brown dwarfs and directly imaged exo-planets. Inhomogeneous clouds, aurorae and magnetic spots have all been p...

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...

Images from Palomar at 2 different infrared wavelengths last night - one that Saturn's methane atmosphere absorbs, and one the it reflects! (The faint point source is the moon, Tethys!) Taken by David Ciardi, Catherine Clark, @lowbacca.bsky.social and Miranda Felsmann; animated by me (and ezgif!)

I'm absolutely delighted to share that my Hubble Space Telescope proposal has been accepted! We will search for the first UV detection of an aurora outside the solar system on the brown dwarf 2M1047, using simultaneous observations from HST and the VLA. Stay tuned for some very exciting science! 🔭📡

Very proud of Cian O'Toole who gave his very first conference talk at #EAS2025 last week. 🔭 He is investigating the drivers of variability in three brown dwarfs using observations from HST, VLA and a new framework for modelling variable atmospheres. Paper is incoming so watch this space! 📄📄📄
