Seeking PhD candidates that want to do a thesis on exoplanet atmosphere retrieval + machine learning inference. Please apply by 31 October to Dr. Max Dax's and my shared project here: is.mpg.de/news/new-max... . Abstract for the thesis project is attached to this thread below!

New unified model of equatorial winds on giant planets helps to explain some of the zonal wind observations 🔭 I and my colleagues have made for Neptune and Uranus over the past few decades - www.science.org/doi/10.1126/...

The phosphine molecule, PH3, has been proposed as a biosignature in rocky planets. In @science.org, Burgasser et al. report phosphine in a brown dwarf atmosphere. "We therefore caution against the use of phosphine as a biosignature". #stellarastro #exoplanet ☄️ www.science.org/doi/10.1126/...

🔭 It's paper day! Today I'm sharing the latest in a series of papers looking at the weather on other worlds, in this case bringing you the weather report from a nearby T-dwarf, SIMP-0136. 🪐 🧵 to follow...

We have job opportunities in the APEx department at MPIA - please spread the word! Postdocs: aas.org/jobregister/... Tenure-track staff: aas.org/jobregister/... Max Planck Research Group Leaders: aas.org/jobregister/... + happy to host ERC, Humboldt, and other third-party funds.

So great to see another incredible JWST variability study by Akhmetshyn et al. on the planetary-mass object SIMP 0136. These kinds of datasets reveal the most important details about the atmosphere and how they change over time. We are officially in in the era of exoplanet weather! 🪐☁️

I rarely see Planetarium Astronomer jobs being advertised in the UK, we have a distinct lack of Planetariums. The Royal Observatory in Greenwich is currently hiring for one! app.vacancy-filler.co.uk/salescrm/Car...

Super excited for this accepted HST+VLA program led by Cian O'Toole, who hopes to expand our knowledge of extrasolar aurorae into the UV 🔭

We are so excited for Dr McCarthy @alliemccarthy.bsky.social to join the group @tcddublin.bsky.social 🪐☁️

Attended my first ever conference last month at #EASCork! Super inspiring to hear about what’s going on in exoplanets and brown dwarfs!

Very proud of Cian O'Toole who gave his very first conference talk at #EAS2025 last week. 🔭 He is investigating the drivers of variability in three brown dwarfs using observations from HST, VLA and a new framework for modelling variable atmospheres. Paper is incoming so watch this space! 📄📄📄

It’s a beautiful day in Cork to kick off our symposium on giant exoplanets and brown dwarfs #EAS2025

Looking forward to speaking at Astronomy on Tap this Wednesday in Cork! 🍻💫 Tickets available at this link www.eventbrite.ie/e/astronomy-...

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

NEWS: #NASAWebb has directly imaged a cold exoplanet in an extremely misaligned orbit for the first time. The observations have surprised researchers in more than one way: webbtelescope.pub/3ZSctun #AAS246 🔭 🧪

Macquarie has put out the call for fully-funded PhD applications in all areas of astronomy, to start January 2026: aas.org/jobregister/... Applications due 2 July to [email protected]. International scholarships will be competitive, typically expecting publication and/or excellent GPA.

Together with Sebastiaan Haffert our review on “High-Contrast Coronagraphy” is out - writing an ARA&A review has been on my academic bucket list, and I’m very proud of the result. It uses the showyourwork! framework, making it a completely reproducible paper. #FAIR #astrodon #exoplanets

Less than a month till the deadline to apply for this PhD place!

The Minister for Heritage has announced that the Historic Astronomical Observatories of Ireland have been added to the World Heritage Tentative List, in a bid to become a UNESCO World Heritage Site
