🔭 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. 🪐

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! 🔭📡

The JWST Weather Report from the Isolated Exoplanet Analog SIMP 0136+0933: Pressure-Dependent Variability Driven by Multiple Mechanisms Isolated planetary-mass objects share their mass range with planets but do not orbit a star. They lack the necessary mass to support fusion in their cores and thermally radiate their heat from formati...

Check out BU PhD-student @alliemccarthy.bsky.social's paper just accepted to ApJL! JWST spectral light curves of SIMP 0136 show clear pressure-dependence, indicating three variability mechanisms: clouds, hot spots and C chemistry. @johannavos.bsky.social is the JWST PI! arxiv.org/abs/2411.16577
