🔭 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. 🪐

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!)

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! 📄📄📄
