SAVE THE DATE! The 11th AAS Topical Conference Series (AASTCS): Exoplanet Atmospheres 2026 will take place in Denver. Join astronomers, planetary scientists & researchers from around the world for an in-depth exploration of one of the most dynamic fields in science today. More details soon 🔭

Evan has extended our cloudy Diamondback evolution models to higher Teff with PHOENIX models at the high end. This permits all model tracks to start at the same young age. We call this model variation Red Diamondback.

Two papers announcing the discovery of a directly imaged 6 Jupiter mass planet around binary system HD 143811 AB Squicciarini+ and Jones+ in Sco-Cen - Keck, Gemini and VLT all imaging this companion and confirmed with several years of common proper motion. #astrodon #exoplanet #exosci

A quick advert for the ✨✨✨Official✨✨✨ release of the Virga cloud code (the python version of everyone's favorite EddySed model by @markmarley.bsky.social and Andy Ackerman). arxiv.org/abs/2508.15102

I liked Caroline Morley's Exoclimes poster describing our Sonora model set so much that I'm going to hang up a replica in my office.

The 51 Peg b postdoctoral fellowship is out and Northwestern is one of the possible host institutions. Come join us! More information about the range of planetary astronomy research and other opportunities (like PI of Keck proposals) here: ciera.northwestern.edu/opportunitie....

We are delighted to announce fourteen postdocs will be joining the CIERA community in fall 2025. Please join us in extending a warm welcome to these fantastic researchers!

Maybe these slow rotating weirdos are binary star systems! Find out more in this @aunz.theconversation.com article by Iris de Ruiter theconversation.com/mysterious-r... 🔭🧪

Tired of wondering which atomic lines are in your spectra? You need: *whose line is it anyway?* An interactive tool for identifying atomic spectral lines. 🧪🔭 #stars install: pip install whoseline source: github.com/bmorris3/who...

Very excited to share that I was selected as a Sloan Research Fellow! Really thankful to all my mentors, colleagues, collaborators, and my amazing research group. Wouldn't have been possible with all of them!

Registration is now open for the (free, hybrid) 2025 Sagan Summer Workshop! This (25th!) workshop will be focused on Exoplanet Demographics and our overall picture of exoplanet populations through various detection techniques. 🪐🔭🧪 nexsci.caltech.edu/workshop/2025/

Final week to apply for the Code/Astro workshop! Come learn about open-source software development in Python.

Excited to share our interdisciplinary work on developing new methods to subtract off the glare of the star to reveal fainter exoplanets. We show in simulation that we can build a full optical model of JWST/NIRCam and generate images of the star to subtract off and reveal faint planets (1/3)

Hey bluesky! Do you want to develop your own open-source software in Python? Apply to attend Code/Astro! Website: semaphorep.github.io/codeastro/ Scroll all the way down for the application link. :) Apps are due Feb 1! (1/2)

Want to learn how to make your astronomy code open source? The Code/Astro workshop is happening this Aug 4-8th at Northwestern! We typically get a strong demand so we ask those interested to fill out an application by Feb 1st. See Sarah's post below for details.

I can validate that working with @philosicist.bsky.social is amazing, and a great opportunity to enjoy sunny San Diego!!

Northwestern press and Nature Astronomy research highlights nicely summarize our new paper on a baby planet’s atmosphere news.northwestern.edu/stories/2024... www.nature.com/articles/s41...

So excited to share the news that Northwestern is joining the GMT consortium! news.northwestern.edu/stories/2024...

Hey folks! Just popping in to announce that the full recording of the 2024 Code/Astro workshop is up on youtube. Playlist here: www.youtube.com/playlist?lis... Code/Astro is a week-long software development workshop for astronomers. More info about the workshop here: semaphorep.github.io/codeastro/

🔭🧪🎢 Check out this awesome Python Notebook that my NITARP alumni made for making SEDs. There is also a Colab version! github.com/jimmynewland...

There is an exciting PhD position available at @diasdublin.bsky.social in the area of planetary magnetospheres and habitable moons with ESA's JUICE mission 🪐🌑☘️ The deadline is TOMORROW and full details are here: www.dias.ie/phd-position... Please share! 🪐🔭

NASA is soliciting additional funded teams to join the Roman Space Telescope Coronagraph Participation Program. Help us demonstrate the technology to image habitable worlds in space! Happy to chat with anyone that's curious about getting involved. nspires.nasaprs.com/external/sol...

Check out BU PhD-student @alliemccarthy.bsky.social's paper just accepted to ApJL! JWST spectral light curves of SIMP 0136 show clear pressure-dependence, indicating three variability mechanisms: clouds, hot spots and C chemistry. @johannavos.bsky.social is the JWST PI! arxiv.org/abs/2411.16577

I am excited to share my third paper of this year, and my first exoplanet paper with @thejason.wang, accepted to ApJL. We detected CO and water in the atmosphere of PDS 70 b, a protoplanet around its natal disk using Keck/KPIC. PDS 70 b shows a stellar-like C/O ratio (!). arxiv.org/abs/2411.15117

A brown dwarf astronomy starter pack. Let me know if you want to be added. It was @markmarley.bsky.social ‘s idea. 🔭 go.bsky.app/UVjXNLA

Hello blue sky! Ready to catch up with friends and colleagues here, and share some my new science in the future 😁
