Anyone at #exoplanets5 ever panicked writing a transit proposal re: how long an exposure *should* be? There are 👍/👎 for both longer/shorter exp so it’s fair to be confused… if you want to learn, find me in poster area A (downstairs) all day Thu! Explanation thread w/ gifs ⬇️

Kicking off the BrinMRC Summer School on Tracer Mixing Across Planetary Scales with Peter Driscoll from Carnegie EPL! I'm excited for the next two weeks focused on numerical simulations of planetary interiors, oceans, and atmospheres and discussions with our students/lecturers.

Come check out our new paper! We detected hydrogen sulfide in the atmosphere of a metal-enriched Jupiter-mass exoplanet! nature.com/articles/s4158…

The 51 Pegasi b Fellowship is officially accepting applications!! Carnegie Science is one of the new host institutions this year and I strongly encourage all those interested to apply! Feel free to DM/email me for details about Carnegie and the Fellowship hsfoundation.org/programs/scien…

Using NASA Webb Telescope, @UMDAstronomy researchers found that exoplanet HD 189733b has trace amounts of hydrogen sulfide, giving it a rotten egg aroma. Sulfur, a building block of planets, could offer clues about other gas worlds in the universe. go.umd.edu/189733b

Jordan Ealy, a #PhysicsandAstronomy Cal-Bridge Doctoral scholar, recently shared their work in the magazine, Diverse: Issues In Higher Education. The article discusses exoplanet research along with the influence of Cal-Bridge on their success. Congratulations Jordan!

.Arjun Savel asks us to consider: Are atmospheres 3D in ways that "actually matter"? E.g. in high-resolution, we have biases particularly because the data is sensitive to dynamical effects (especially UHJs). "Perhaps regular hot Jupiters are best for 1D retrievals". #twohorses

My paper + spectrum model that I developed with Megan Bedell, Erik Petigura, and Melissa Ness is on arXiv today: arxiv.org/abs/2407.19016, and the open-source model is on GitHub: github.com/isabelangelo/g…! Our model characterizes stars with published RVS spectra from Gaia DR3:

WASP-39 b is a giant gas planet with eternal daylight on one side and eternal darkness on the other. Using NASA Webb Telescope, @UMDAstronomy researchers discovered other key differences between the dawn and dusk sides of this distant world. Read more: go.umd.edu/WASP-39-b

Applications are open for Max Planck Research Group Leaders! this is an amazing opportunity to build an independent research group that comes with 2.7 MEuro support over 6 years. If you're interested in being hosted Max-Planck-Institut für Astronomie, please contact me! mpg.de/career/max-pla…

My first PhD paper is on arxiv today! Rotating planets are slightly wider at their equator compared to the poles. Saturn in our Solar System (below, minus the rings), is about 10% oblate! Can we detect this shape difference in transits from JWST? (1/N) arxiv.org/abs/2410.03449

UMD UMD GRADMAP is now accepting applications for our winter workshop! The winter workshop is a free, week-long virtual workshop to build programming and research skills for physics and astronomy. Workshop Dates: Jan 6-10, 2025 UMD Science @UMDAstronomy 1/4

Doctoral student Sathvik Nair (Sathvik) uses large language models to decode human cognition and integrate natural language processing with psycholinguistics. His work is supported by a coveted U.S. National Science Foundation Graduate Research Fellowship. Read more: go.umd.edu/1szd

My new paper is out today on a catalog of stellar companions with pulsation timing in TESS photometry! arxiv.org/abs/2410.19729 Paper thread below ⬇️

My latest paper is on the arXiv! We take a look at the dayside of ultra hot Jupiter WASP-121 b with IGRINS on Gemini South (rip) and show you can simultaneously measure both the C/O and refractory/volatile ratios with a single instrument arxiv.org/abs/2410.19017
