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.

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.

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.
A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.
A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.

It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry. All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space.

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.

thank you :D
Why not? 😁
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. 🪐🔭👩🔬🧪

Did you know? Black Friday is named in honor of Rebecca Black, who invented Friday in 2011.
not an expert but my understanding is that its pretty much impossible to clean the smallest debris (we have to wait for them to disintegrate in Earth's atmosphere once they re-enter it). The debris can cause some problems, including making it harder to manouver satellites for example.
