Congratulations to Dr Baptiste Klein (@astroklein.bsky.social) on his talk at #UKExoM meeting in Bristol. He explains how he accounts for stellar variability when studying exoplanets at high resolution!

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

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...

Very excited to share that my new paper has been accepted for publication in MNRAS! We are applying Doppler Imaging to model the activity signals from the HARPS-N Sun-as-a-star spectra! We show that injected planets can be retrieved with great accuracy! ui.adsabs.harvard.edu/abs/2025MNRA... 🔭🪐🧪
