🔭 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. 🪐

ICYMI: 📰 The Leverhulme Trust September Newsletter is out!

Thrilled to share that I’ve been awarded a 3 year Leverhulme ECF!

I’ll use global modeling with high-res regional ‘nests’ to take a closer look at Jupiter’s polar vortices.

As part of the project, I’ll incorporate this functionality into Isca (via a new dynamical core).

Very excited to begin!

Congrats @timlichtenberg.bsky.social !! For the Early Science Award by the @europlanetmedia.bsky.social super well deserved and amazing talk 🤩🥳🥳🥳!

A Stellar Revolution: How Open-Source Tool MESA Changed the Way We Study Stars A Stellar Revolution: How Open-Source Tool MESA Changed the Way We Study Stars on Simons Foundation

Great article from the Simons Foundation about the open source MESA stellar evolution code, which has a had a huge impact on astrophysics over the past 15 years.
I had not heard that the code's architect, software guru Bill Paxton, had passed away in July.

A prudent planetary limit for geologic carbon storage - Nature A risk-based, spatially explicit analysis of carbon storage in sedimentary basins establishes a prudent planetary limit of around 1,460 Gt of geological carbon storage, which requires making explicit decisions on priorities for storage use.

Exoplanets 🔭 and Planetary Science 🪐 : Two Different Worlds 🌍 ?

What can planetary scientists learn from exoplanet research? Read all about it in our interview with @timlichtenberg.bsky.social

Eleanor Lutz - An Orbit Map of the Solar System A map visualizing the orbit paths of 18,000 asteroids in the solar system.

At a planet formation seminar today, the speaker used these amazing maps of the Solar System from Eleanor Lutz: she has a great blog post on how she took 18000 asteroids, on a log(size) and log(orbit) plot, with 40-year orbit trails, to create this #planetsci #dataviz

Two postdoc jobs available on our Arctic Butterflies project! (Not actual butterflies - basically Arctic dynamics and predictability - the butterfly effect in the Arctic...)

Oxford job: tinyurl.com/yc6h4b35

Reading job: tinyurl.com/ypn75jh2

Please help spread the word!

I updated my website to have an interactive webpage where you can plot the exoplanet population, select different parameter spaces to explore, and overlay the observed and planned JWST observations. I think this will be a useful tool for proposal planning: www.astrojake.com/exoplanets

Just how bad will climate change get? The only way to know is to fund basic research Predictions of climate change are uncertain. That’s why we need to keep finding out how our atmosphere works.

📢📢 New preprint alert! 📢📢

Radiation is a key piece of climate models, but comes with a trade-off: use an accurate scheme (which is difficult to understand), or a simple scheme (which is not very accurate)...

Here I introduce a scheme which bridges this gap!

arxiv.org/abs/2508.09353

Under climate change, the polar regions warm *faster* than the rest of the world ("polar amplification", PA).

But, is this always the case?

In this preprint (with Tim Merlis) we studied the 'state-dependence' of PA—feedback welcomed! :)
