#NASAWebb has found the first direct evidence of potential moon formation around a giant exoplanet. The discovery is shedding light on how such systems evolve and why moons could be potentially habitable worlds: https://bit.ly/46xGodN 🔭 🧪

An illustration of a young planet with a surrounding disk of dust and gas potentially forming moons. The planet, which appears dark red, is shown at lower right, circled by a cloudy, clumpy reddish orange-colored disk. The host star appears at upper left, and glows yellow, with its own reddish disk of debris. The disk that surrounds the planet takes up about half the illustration. The black background of space is speckled with stars. At the bottom of the illustration, graphics of molecules are listed in the following order: Acetylene, Carbon Dioxide, Ethane, Benzene, Hydrogen cyanide. The words Artist’s Concept appear at upper right.

🪐🔭 JWST is letting us learn about disks around PLANETARY-MASS OBJECTS!!!

Sierra Grant @sierragrant.bsky.social · 19d

Today is a special paper day for me: for the first time we can do chemistry in a circumplanetary disk around a planetary-mass companion! Gabriele Cugno and I used JWST to tease out the signal of CT Cha b, finding a rich carbon chemistry (7 molecules + 1 isotopolog detected)! arxiv.org/abs/2509.15209

Now published in AJ! Get in here this system is crazy iopscience.iop.org/article/10.3...

Another MINDS JWST paper! We explore the stark transition from H2O-dominated spectra in Sun-like systems to the carbon-rich chemistry seen for low-mass objects. We don't know exactly what is driving this trend, but we explore the possibilities that may be acting in concert.

Congratulations to Dr. Allison McCarthy, who successfully defended her PhD “The Physical Basis for L and T Dwarf Variability” on Friday! Allie is now off to Trinity College Dublin for a postdoc with the ExoAimsir group led by Prof. Johanna Vos! 🪐🔭 @alliemccarthy.bsky.social @johannavos.bsky.social

New paper on arxiv! My colleague Juliana García-Mejía analyzed data from several facilities searching for a transit of the long-period (542 d) super puff HIP 41378 f. The full transit is 19 hours long, but we detected it using a few "snapshots" from multiple observatories.

A light curve showing a transit of HIP 41378 f. The data span three nights and were taken with multiple facilities. On the second night, the data from four different facilities are decremented by approximately the transit depth expected for HIP 41378 f.

And here's the 40-degree spherical harmonic expansion of my cat 😭😭😭

Just found out starry (starry.readthedocs.io/en/v1.1.0/) lets you project any image you want onto a sphere, so here's the 40-degree spherical harmonic expansion of Jupiter. 🪐🔭

Patrick Tamburo @tamburo.bsky.social · Jun 16

Agreed! And I think it will be very informative to watch how the spot(s) evolve over the coming years

Patrick Tamburo @tamburo.bsky.social · Jun 16

Thank you Johanna! :)

Patrick Tamburo @tamburo.bsky.social · Jun 16

This work has been submitted to AJ and we welcome any comments! #exoplanets ⭐🪐🔭

We simultaneously modeled several transit observations, finding that the rotational light curve AND the changes in the transit shapes can be described by a planet transiting a large polar spot.

Patrick Tamburo @tamburo.bsky.social · Jun 16

We used 124 nights from the Tierras Observatory (sites.harvard.edu/tierras-obse...) to measure the star's rotation period, which is 11 days.

A light curve of TOI-3884 b showing its 11-day rotation period.

Patrick Tamburo @tamburo.bsky.social · Jun 16

TOI-3884 b is a planet around an M dwarf whose transits show persistent spot crossings. We show that the star's rotational and spot-crossing variations can be modeled with a misaligned planet transiting a large polar spot (confirming last week's results from Mori et al.)

Thank you Brett!

Patrick Tamburo @tamburo.bsky.social · Jun 13

Now published in AJ! We used Tierras to measure the 23-day rotation period of a K dwarf and found that the orbit of its transiting planet is aligned with the star's spin axis. Stay tuned as we measure true obliquities for a larger sample!
