seven panel figure showing different JWST transits of TOI-3884 b with a persistent spot-crossing event. TOI-3884 b orbits the pole of a small M dwarf star. the shape of the spot-crossing event changes slightly between each transit. each subpanel has a graphical representation of what the spot looks like during each transit.
really exciting work lead by Catriona Murray! TOI-3884 b is a planet on a polar orbit around an M dwarf. The transit has a persistent starspot crossing event. Using JWST, we measured the properties of the starspot and the Prot of the star 👀 arxiv.org/abs/2603.15414

Yuk was new faculty when I was an undergraduate studying planetary. It always felt like he was unchanging and ageless. He made so many contributions while remaining positive and joyful. Truly will be missed.
I feel like releasing JWST #cycle5 results on Friday is like firing employees on Fridays
I am hiring a postdoc in exoplanet atmospheres! (ASIAA, 4yrs, funded through 2030)
Job ad here. Feel free to reach out if there are any questions!

PS. There’s also another postdoc position in cosmology with an awesome colleague
Feel free to reach out if you have any questions about ASIAA or life in Taipei!
The institute has a vibrant research environment, with 20+ postdocs from diverse international backgrounds. ASIAA is also part of the ELT/METIS instrument design and science team and is involved in the MagNIFIES project for Magellan/GMT.
Excited to share some great postdoctoral opportunities available at ASIAA, Taiwan.
— especially the Distinguished Postdoctoral Fellowship, which is an independent 2+2 year position.

Or you have to publish your previous data before being allowed to submit again

So excited to host my first visitor, Prof. Xinting Yu @joneskuma.bsky.social, who gave a wonderful colloquium taking us from organic particles on Titan to protoplatary disks. Can interstellar organics promote grain growth in a disk? So much to explore in the lab!
I wrote a research note about the recent publication of the MIRI/LRS spectrum of K2-18b. The authors had claimed the detection of potential signs of life. I find the data to be consistent with a flat line 🔭🧪
For our #JWSTCycle4 proposal on atmospheric characterization (unrelated to habitability nor astrobiology), the 1st weakness is "not clear enough what implications would it have for other classes of space creatures" - by reviewer 1 not reviewer 2

Bizarre mineral clouds on a hot giant planet.
In 2023, JWST found quartz (SiO2) clouds in the hot Jupiter WASP-17b.
WASP-17b will be revisited with JWST to discover the specific crystal structure of these quartz clouds. We'll understand these exotic exo-clouds like never before!
