I wrote another paper! And yes it's about brown dwarfs wait don't go anywhere they're really neat

JADES: An Abundance of Ultra-Distant T- and Y-Dwarfs in Deep Extragalactic Data
Ultra-cool T- (T$_{\mathrm{eff}} \approx$ 500 - 1200 K) and Y-dwarfs (T$_{\mathrm{eff}}$ $\lessapprox 500$ K) have historically been found only a few hundred parsecs from the Sun. The sensitivity and ...

I’m thrilled to announce a new paper that went up on the arXiv last night: arxiv.org/abs/2510.02260! The paper finds and maps the connections between clouds, temperature structure, and chemistry in the isolate exoplanet analog SIMP 0136. Very grateful to all my collaborators and co-authors!
Mapping the Cloud-Driven Atmospheric Dynamics & Chemistry of an Isolated Exoplanet Analog with Harmonic Signatures
Young planetary-mass objects and brown dwarfs near the L/T spectral transition exhibit enhanced spectrophotometric variability over field brown dwarfs. Patchy clouds, auroral processes, stratospheric ...

Outstanding new paper from Evert Nasedkin on the variable, isolated exoplanet analog, T dwarf, SIMP-0136! Time resolved atmospheric retrievals find temperature driving variability and potential auroral signatures (stratospheric temperature inversion)!
🔭 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. 🪐

It's NIRPS day! Today we are publishing the first results of the new near infrared planet hunter. A high resolution spectrograph with YHJ coverage and capable of measuring radial velocities with a precision better than 1 m/s.
We debut it with the detection (in the NIR) of Proxima b. #exoplanets 🔭

If you could hear in the infrared, what would CO2 sound like? We calculated this recently for a Gen Ed course, and the result is a little eerie.
Results were generated by mapping IR frequency in inverse cm to sound frequency in Hz.

Good morning #aas245! My students Peter Kearns and Francis Cocchini will be presenting a talk on 1D mapping brown dwarf atmospheres with ground-based photometry on Wednesday at 11:20 AM (319.07) in Stars/Cool Dwarfs/Brown Dwarfs II. Hope to see you there!
