The deadline for the 51 Pegasi b Fellowship is right around the corner. www.hsfoundation.org/programs/sci... Interested in theory, modeling, and discovery? Join @nixonmatthew.bsky.social, Sagnick, and me at the Exoteric Lab at ASU @seseasu.bsky.social

What does it mean to detect a gas in an exoplanet atmosphere? Listen to what @nixonmatthew.bsky.social and I had to say. It was a pleasure chatting with @startswithabang.bsky.social !!

We need to understand the limits of our models and our data for reliable interpretations of exoplanetary spectra. First paper by my first PhD student! Happy advisor moment. Congrats @yoavrotman.bsky.social Check out his paper on the Arxiv and his thread below #exoplanets 🔭

I agree with you that saying K2-18 b “can’t” have an ocean or “isn’t” an ocean world is a stretch - we can’t totally rule it out with the present data, but it does appear that Neptune-like or gas dwarf models are consistent with what we know about the planet and require much less fine-tuning

Here's my follow-up story on K2-18b, the distant planet where scientists claimed to see a possible sign of life last month. In three preprints, other researcher argue that the signal is noise. nyti.ms/4jaqQRv

Good to see Pica-Ciamarra, Madhu+ engage with our work and correct claims from last month. Following our recommendation to expand the model space, they now find: ‘No molecule reaches 2σ significance when allowing for an offset…’ 𝐍𝐨 𝐛𝐢𝐨𝐠𝐚𝐬𝐞𝐬 𝐚𝐟𝐭𝐞𝐫 𝐚𝐥𝐥!

Still trying to process that HST and JWST are looking at the same target **simultaneously**. Moments like this fuel the part of me that grew up in awe of space and somehow ended up in a job where this is real. 🔭

Working on this project was both fun and rewarding. I’ve kept Magritte’s The Treachery of Images in my office since my master’s—a reminder that definitions, like models, are not the thing itself. Context matters. So do the assumptions we often forget we’re making. Check out Matt's thread about it!

3 Gates Cambridge Scholars - @luiswel.bsky.social, @rebeccacharbon.bsky.social & Yinuo Han - debate planets, space and the meaning of life in the latest episode of our So, now what? podcast - www.gatescambridge.org/about/news/w... @uniofcam.bsky.social @cambridgeastro.bsky.social #GatesCambridge25

Thrilled to welcome Matt Nixon and @sagnickastro.bsky.social to ASU! A core part of the 51 Peg Fellowship is community—and I’m excited to build one alongside them. We’re ready to push boundaries, think creatively, and make the most of this moment. 🪐🚀 🔗 bit.ly/41WLH48

I'm excited to be in DC this week to present at the #GiantMagellan2023 Community Science Meeting on #Exoplanets. I'll give a review talk on the rapid development of the field. What are your favourite model/observation results from the last 5 years? I'll make sure to give you a shout out!

Well, I've made the jump thanks to @afeinstein20.bsky.social. Hopefully I will be more active here than in the other place. The less happy place.
