🚨 The schedule for the MEME 2026 main event is ready 🚨 Join us on January 30th at 17:00 (CET) to hear the talks by Anja C. Andersen and Adam Dipert 🔭🧪 ✨ If you want your memes featured in this year’s exhibition please submit them through our website asap ✨ massiveexoplanetmemeexhibition.com/home

Deadline is 15th of Jan, so there is still time to apply! :)

Happy to share the first paper from the SPACE Program, led by my student Angelique Kahle! she observed a hot little sub-Neptune, HD 86226c (Rp = 2.3 Re; equilibrium temp = 1300 K). arxiv.org/pdf/2507.13439 The spectrum is *really* flat ! here's the amplitude compared to other gaseous planets.

A companion star …. Inside Betelgeuse’s atmosphere…. You think you know some stuff about the Universe but there’s always more surprises! 🙃🔭✨

My paper with Tom Evans-Soma and Nathan Mayne on magnetic drag models is now accepted and up on the arXiv. For a quick summary, look at the PDF of my Exoclimes poster that I shared last week. www.arxiv.org/abs/2507.08511

Excited to be at Exoclimes (@exoclimes.bsky.social) this week! Come find me at poster 139 🪐 I'm building a retrieval framework to help make sense of variability in brown dwarfs and directly imaged planets. Come say hi, and we can nerd out about variable atmospheres 😊

Since many people can't make it to Exoclimes, here is my poster looking at the geometry of magnetic drag models in hot Jupiter atmospheres. There are many caveats about the applicability of these models, but they're a first step in including dayside coupling. www.duncanchristie.net/s/exoclimes_...

As I sit at Exoclimes listening to a Zoom talk from the UK, I thought I'd share this again. When choosing where to host international meetings, we need to consider the ability of attendees to get visas in a timely manner.

Introducing...your sneak peek at the cosmos captured by NSF–DOE Vera C. Rubin Observatory! Can you guess these regions of sky? This is just a small peek...join us at 11am US EDT for your full First Look at how Rubin will #CaptureTheCosmos! 🔭🧪 #RubinFirstLook ls.st/rubin-first-look-livestream

It's the biggest question there is: are we alone in the Universe? Having the tech to probe the chemical composition of distant planets is 🥳, but as this is just a 3σ result (as likely to be noise as it is likely that today is your birthday) take it with a pinch of salt.👇More on the heated debate👇 🔭🧪

An astonishing headline reporting on new observations from a team led to Nikku Madhusudhan claims they’ve found ‘hints of life’ on a planet orbiting a dwarf star some 124 light years away. What’s going on? (1/n) www.bbc.co.uk/news/article... 🔭 🧪

At some point we need to have a discussion about the ethics of participation in press releases as scientists. From today’s K2-18b saga, Nikku Madhusudhan in the press release says ‘The signal came through loud and clear’ (1/n)

My new paper with Feng Ding and Jun Yang has been accepted at ApJ: arxiv.org/abs/2504.05233. In this study, we find that lower-tropospheric radiative heating is necessary but not independently sufficient to form the NAIV. Instead, the dynamic heating induced by large-scale subsidence is essential.

If you or someone you know are interested in the postdoc or PhD positions at the IWF (OEAW) in Graz, in the exoplanets weather and climate group, remember I am available to talk about my experience 🚩

What do people use to archive their twitter accounts? I want to finally do this and delete my account for good.

New JWST science by Nick Tusay of Penn State! Thanks @astrolisa.bsky.social for the very good writeup! www.sciencenews.org/article/exop...

Exoplanet memes for all the family 🔭🪐🧪👩‍🔬

After years of sweat and tears, my PhD baby is out of the oven. I currently do not have the energy to write a thread about it. In summary: atmospheric modelling with self-consistent microphysical cloud formation is hard. Don't ignore clouds, model them properly. 🪐🔭👩‍🔬🧪 arxiv.org/abs/2501.05521

After years of waiting for another discovery of these bad boys (because I spent way too much time modelling them), finally another one has been found with TESS!!!!

REMINDER: The deadline for applying for the summer internships at the MPIA is next Wednesday, the 15th of Jan! Opportunities open for bachelor and masters students from all over the world! 🔭🧪👩‍🔬🪐⭐

🚨🔔 Job alert 🔔 🚨 ERC positions in our E-BEANS team @tcddublin.bsky.social ☘️ on exoplanetary systems (disks/long period planets/volatile delivery), starting Sep ‘25! ☄️🪐💿 🔭 3-yr Fellow: tinyurl.com/5n77ucnk 4-yr PhD: tinyurl.com/bdb3xyp3 Deadline Jan 6th ⏰ Please spread the word!

The Max Planck Institute for Astronomy Summer Internships are open for applications! This is an opportunity for bachelor and masters students 🤩 If you are interested in doing some exoplanets research, contact me! More info: www.mpia.de/en/careers/i... 🔭🪐⭐🧪👩‍🔬

🚨🚨 I'm hiring!!! 🚨🚨 Postdoc and PhD positions available to join my ERC project Exo-PEA at @tcddublin.bsky.social. The project aims to understand weather in giant extrasolar worlds ☁️⚡🪐 📆 Deadline: Jan 6th Postdoc ad: tinyurl.com/2ufcwvxf PhD ad: tinyurl.com/5amcea6p Please share widely! 🔭🪐

Did you know? Black Friday is named in honor of Rebecca Black, who invented Friday in 2011.

People who use wavenumber instead of wavelength: who hurt you? 🪐✨️🔭

got this in the mail today ✨️❤️🪐

Optimist: The cup is half full Pessimist: The cup is half empty Exoplanetary scientist: We've detected water in the cup!

For the record, the grad student who made the discovery is Madyson Barber, a NSF Grad Research Fellow at UNC Chapel Hill, who led the Nature paper on the result. This is her 4th first author paper.

If you wonder what an astrophysicist does on a friday night: I watch portuguese telenovelas and play stardew valley ✨️ Have to catch up on GBBO soon tho!

Go be one of the most useful people in exoplanet science. This research desperately needs to be done.

Is chatting at the cinema during a film a thing now? Why do people not go to a cafe instead? Where is the self-awareness?

To my new followers: Hello! I'm Beatriz, an exoplanet scientist 🪐 I am currently a postdoctoral researcher at the APEx department in the Max Planck Institute for Astronomy ✨️ I am a modeller and spend most of my days modelling all kinds of exoplanets (and brown dwarfs) I love music and coffee ☀️

Me and Celeste are currently moving to Heidelberg to start our new science adventure! Happy to share that tomorrow I officially start my first postdoc at APEx (MPIA) working with Paul Molliere on variable brown dwarfs (and not only). ✨️

Back here ✨️ I guess the most relevant thing that has happened with my life is that I finally have a PhD in Astrophysics 🪐 Some pictures from my defence with several different moods!

Today I was introduced to what was described as the Worst Plot In Exoplanet Science, and frankly, it is a work of art

If you are thinking of applying to the postdoc position in exoplanet atmospheres at the University of Copenhagen, please feel free to reach out to me and ask any questions about my experience there 🙃

If you are thinking of applying for the postdoc available in exoplanets at the Centre for Exolife Sciences, Niels Bohr Institute in Copenhagen , please please reach out to me, I'd be happy to share my experience as a PhD there with you. 🙂

Excited to share the 1st direct evidence of quartz clouds in the atmosphere of a transiting #exoplanet! With #JWST MIRI we found nanoparticles of quartz, SiO2, causing a spike in the planet's spectrum at 8.6 micron unveiling the Oxygen locked in the clouds doi.org/10.3847/2041...

I love this Radiohead song

You don't really know what postdoc applications season is until you go through it yourself, do you? 😭🫠

I’m hiring PhD students and postdocs to my new extragalactic stellar streams group U. Copenhagen. Please reach out if you have any questions and share this if you know anyone who might be interested. PhD link: jobregister.aas.org/ad/e9fe0095 Postdoc link: jobregister.aas.org/ad/8218d16b

Congratulations to ISRO and India for landing Chandrayaan-3 on the Moon! 🧪🔭

Currently at the Sagan workshop! Yesterday I did some data reduction for the first time in my life... something I never thought I'd get my hands on as a modeller Anyways, I do have a poster on how we can use some peculiar objects to constrain the composition of small rocky planets! #astro

the two most common follow-up questions at any astronomy conference 🧪

Just moved in so here is an intro: hello cloud free skies! I am Beatriz, a (soon to be) final year PhD student at the University of Copenhagen and the Space Research Institute (IWF) in Austria. I study (model) dust in exoplanets, from evaporating rocky worlds to cloud formation in gas giants ☁️
