VLTI/GRAVITY Observations of AF Lep b: Preference for Circular Orbits, Cloudy Atmospheres, and a Moderately Enhanced Metallicity

William O. Balmer, Kyle Franson, Antoine Chomez +26

Direct imaging observations are biased towards wide-separation, massive companions that have degenerate formation histories. Although the majority of exoplanets are expected to for…

easyCHEM: A Python package for calculating chemical equilibrium abundances in exoplanet atmospheres

Elise Lei, Paul Mollière

For modeling the spectra of exoplanets one must know their atmospheric composition. This is necessary because the abundance of molecules, atoms, ions and condensates is needed to c…

Water depletion and 15NH3 in the atmosphere of the coldest brown dwarf observed with JWST/MIRI

H. Kühnle, P. Patapis, P. Mollière +21

With a temperature of K WISE0855 is the coldest brown dwarf observed so far. Using the James Webb Space Telescope (JWST) we obtained observations that allow us to charac…

BOWIE-ALIGN: JWST reveals hints of planetesimal accretion and complex sulphur chemistry in the atmosphere of the misaligned hot Jupiter WASP-15b

James Kirk, Eva-Maria Ahrer, Alastair B. Claringbold +23

We present a transmission spectrum of the misaligned hot Jupiter WASP-15b from 2.8-5.2 microns observed with JWST's NIRSpec/G395H grating. Our high signal to noise data, which has…

The ESO SupJup Survey III: Confirmation of 13CO in YSES 1 b and Atmospheric Detection of YSES 1 c with CRIRES+

Yapeng Zhang, Darío González Picos, Sam de Regt +14

High-resolution spectroscopic characterization of young super-Jovian planets enables precise constraints on elemental and isotopic abundances of their atmospheres. As part of the E…

Standing on the Shoulders of Giants: A Comprehensive Spectroscopic Survey of Transiting & High-Contrast Giant Planets

Munazza K. Alam, Emily Rickman, Kielan Hoch +6

We propose a comprehensive survey of giant planets ranging from close-in highly irradiated hot Jupiters to young, wide-orbit directly imaged planets. The combination of two establi…
