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

arxiv.org/abs/2510.00111

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. 🪐

🧵 to follow...

Looks like it’s a strong possibility

Really nice opening drive

I loved this paper, particularly the comparisons to GCMs! I would definitely love to see more Brown Dwarf Doppler imaging studies!

Perfect story for morning drive to work! Loved it!

The original RE4 marked the shift in the series away from survival horror to action as I recall; I wasn’t a fan of RE5/6 but still really liked RE4

I need to play this; haven’t played RE4 since the PS2 days but loved the RE2 remake

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 🔭

The IAC leads the first scientific results of NIRPS, the new infrared exoplanet hunter

The new infrared spectrograph NIRPS, built with the participation of the Instituto de Astrofísica de Canarias (IAC) and installed on the 3.6-metre telescope at ESO’s La Silla Observatory in Chile, has...

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.

It’s thought to be a shallower ionic ice layer, perhaps explaining the extreme multi-polarity in Neptune’s magnetic field.

Neptune’s magnetic field is thought to be generated in an ionic layer of ice (water, methane and ammonia).

Thanks! Excited to hear more about the new project!

This wouldn’t happen to have molecular absorption bands too?

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!

I would love a Sonic Adventure 1 & 2 Remaster (also from Sega, I really want a Shenmue remake/remaster with modern controls).

She is such an amazing writer, such a powerful book!

Michael Plummer @magmaskies.bsky.social · Nov 18

Love this idea! Would you be able to add me as well?

Michael Plummer @magmaskies.bsky.social · Nov 17

Glad to meet you! I research brown dwarf and exoplanet atmospheres with a current focus on the sources of variability. I am a new assistant professor at the US Air Force Academy.
