Congratulations, @nichollsh.bsky.social! Your thesis was a joy to read, and it was great to get to know you over the past 1.5 years. I look forward to seeing the research that you and Oli get up to at Cambridge. Perhaps almost as impressive was your AOPP champagne cork shot! Video below.

Impressive work, Richard!
Congratulations to Dr Richard Chatterjee who just successfully defended his DPhil! I’m so proud of him! He is a rockstar and is revolutionising our understanding of atmospheric escape. Here’s to more science together 💜

Acquiring a white bowtie has been on my to-do list since the last viva I served as an internal examiner for! I'll be sure to get one by @nichollsh.bsky.social's viva in January.
Congratulations to Dr. Richard Chatterjee, my DPhil student who passed his viva on atmospheric escape today and is off to a position at Leeds. (Me on the left, his examiners Garcia-Muñoz and Tad Komacek on the right -- Tad and Richard are in the traditional subfusc, except should be white tie)

Very exciting and well deserved @ntlewis.bsky.social, and I'm looking forward to seeing what you find!
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!
In this groundbreaking project, Early Career Fellow @ntlewis.bsky.social @exeter.ac.uk, employs techniques from terrestrial meteorology and draws together contrasting theories to form a holistic view of Jovian polar atmospheric dynamics. www.flipsnack.com/leverhulmetr...

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.

In our now-published paper we model the early history of three exoplanets to specifically study the role of tidal heating on their capacity to solidify. A physically robust feedback mechanism can keep them molten, even with relatively thin atmospheres, which may extend to lots of rocky exoplanets.

In our new paper we model the complete evolution of L 98-59 d from 'birth' up to the present day. We show that it cannot be a gas dwarf or a water world; it's a 'hybrid' planet with an H2-rich atmosphere containing H2S and SO2 (photochemistry!), and a deep magma ocean.
