Pretty neat: using time-resolved spectra of an exoplanet transit, you can get temperatures and composition as a function of planet longitude. Another way to look at the 3D structure of Hot Jupiter atmospheres, thanks to JWST. @lili-alderson.bsky.social+ arxiv.org/abs/2610.18806 🧪🔭 #exoplanets

Temperature as a function of longitude (angle w.r.t. anti-stellar point) in a polar plot. Temperatures are much cooler on the nightside than on the day-side (about 900 versus 1500 K).

Forming Worlds Lab @formingworlds.space · about 16 hours ago

Posted to arXiv last month and submitted to The Astrophysical Journal, work led by PhD student Emma Postolec: 🌋 "Evolutionary pathways toward survival of a thick CO2- or SO2-rich atmosphere on the lava world TOI-561 b" Read: arxiv.org/abs/2609.03144 #Exoplanets #PlanetaryScience

Portrait of lead author Emma Postolec with a card showing the paper title "Evolutionary pathways toward survival of a thick CO2- or SO2-rich atmosphere on the lava world TOI-561 b" and the co-author list.

Three-panel plot of the 19 simulated TOI-561 b cases that match observations at 11 Gyr. Panel a shows temperature-pressure profiles reaching 3400-3500 K at 1,000 to 30,000 bar over a magma ocean surface. Panel b shows stacked bars of atmospheric volume mixing ratios, split into CO2-dominated cases at low S/H and SO2-dominated cases at higher S/H. Panel c compares initial and present-day C, H, O, N, and S budgets split between atmosphere and interior.

Max Planck Institute for Solar System Research @mpsgoettingen.bsky.social · 3 days ago

Young, close-in #planets love to live dangerously: They can provoke stellar #flares that backfire. At #mpsgoettingen, Ekaterina Ilin heads a new Max Planck Research Group and #ERCStartingGrant to study this self-destructive interaction. www.mps.mpg.de/young-close-... @erc.europa.eu #exoplanets

The close-in planet’s magnetic field interacts with that of its host star, thereby triggering a massive solar flare.

I had an absolutely fantastic time talking about colliding exoplanets as part of Pints of Knowledge at Big Penny Social in Walthamstow, and spent over half an hour answering many excellent questions from the audience! #exoplanets #astrodon #outreach

An image of the Extremely Large Telescope shrouded in mist with a rising sun is projected on a large screen, with me in a blue and white checked shirt standing in front of it with me waving my arms around excitedly and talking to the audience.

Interesting new project in citizen science, from the CHEOPS space telescope. I'm involved there as a volunteer. There are, also, further interesting variable sources, around targets preselected for potential new exoplanets. www.zooniverse.org/projec…. #exoplanets #variablestars #stellarastro

I provided some comments in this news article about an #exoplanet candidate discovery from someone using AI who posted the finding to social media. tl;dr: This is a planet candidate. Confirmation requires follow-up, which, for now, still needs humans. 🔭 gizmodo.com/did-claude-h...

Did Claude Help an Amateur Astronomer Discover a New Planet?

Billions of exoplanets are believed to be out there awaiting discovery. AI—with its ability to sift through mountains of data—could speed that process along.

I remain not a fan of the practices behind LLMs, and skeptical about a lot of their publicity, but it's really undeniable that they can help someone that knows the concepts and is grounded in their questions to push further that what they could otherwise do #exoplanets #astronomy
