Do you love WASP-107 b? Do you love making use of *both* ground VLT + space JWST obs to detect molecules in a "warm" (Teq<800K) #exoplanet in transmission, even in a crazy confusing cloudy atmosphere?! 🚨 It's PAPER* DAY! Which means #scicomm thread! 🧵⬇️🔭🪐🧪 *pre-print! arxiv.org/abs/2508.18964

Paper day! You're doing ground-based high-resolution exoplanet transmission spectroscopy and want to analyse the planet—not the star or Earth's atmosphere. Is there a way to disentangle your spectrum *without* destroying the planet signal? arxiv.org/abs/2509.12737 🧵⬇️ 🔭 #exoplanets #astromethods

TSD: An inverse problem approach for recovering the exoplanetary atmosphere transmission spectrum from high-resolution spectroscopy

Our ability to observe, detect, and characterize exoplanetary atmospheres has grown by leaps and bounds over the last 20 years, aided largely by developments in astronomical instrumentation; improveme...

VLT/CRIRES+ observations of warm Neptune WASP-107 b: Molecular detections and challenges in ground-based transmission spectroscopy of cooler and cloudy exoplanets

Atmospheres of transiting exoplanets can be studied spectroscopically using space-based or ground-based observations. Each has its own strengths and weaknesses, so there are benefits to both approache...

<skeets into room at full speed> Hi astro bluesky—it's paper day! I dove into optical M/K dwarf spectra—rife with molecules as they are—& found success with a data-driven 🌈 model (i.e. ML) vs physical models. 1) 🟦🌈 recovery 😌 2) 🟥🌈 recovery 😌 3) Physical model vs ML 🙃 arxiv.org/abs/2402.14639 🔭
