Native-resolution retrievals of VHS 1256-1257 b spanning the JWST/NIRSpec wavelength range: Chemical composition of a partially cloudy atmosphere
S. de Regt, N. Whiteford, B. E. Miles +3
The wide wavelength coverage and sensitivity offered by JWST enable detailed analyses of extrasolar atmospheres. At its highest resolution (R~2700), NIRSpec measures the absorption…
The ESO SupJup Survey XI. Atmospheric properties of six isolated M- and L-type dwarfs with CRIRES+
C. R. Malcolm, N. Grasser, I. A. G. Snellen +9
The distinct formation pathways of brown dwarfs and giant exoplanets may be encoded in their atmospheric composition. We present atmospheric retrievals for six isolated brown dwarf…
Strong and variable stratospheric CO emission from lava-planet 55 Cnc e observed with NIRCam/JWST
Ignas Snellen, Yamila Miguel, Leoni Janssen +4
Some rocky planets orbit so close to their host stars that stellar heating melts their surfaces. They offer a rare glimpse of planets in a magma-ocean state, providing an observabl…
The ESO SupJup Survey. X. A carbon isotope contrast in the young ROXs 12 system
N. Grasser, I. A. G. Snellen, S. de Regt +7
Emerging research suggests that elemental and isotopic ratios of exoplanet and brown dwarf atmospheres may serve as potential tracers of their formation pathways. The ESO SupJup Su…
Conditions for radiative zones in the molecular hydrogen envelope of Jupiter and Saturn: The role of alkali metals
Louis Siebenaler, Yamila Miguel, Sam de Regt +1
Interior models of gas giants in the Solar System traditionally assume a fully convective molecular hydrogen envelope. However, recent observations from the Juno mission suggest a…
The ESO SupJup Survey IV. Unveiling the carbon isotope ratio of GQ Lup B and its host star
D. González Picos, I. A. G. Snellen, S. de Regt +4
The carbon isotope ratio () is a potential tracer of giant planet and brown dwarf formation. The GQ Lup system, hosting the K7 T Tauri star GQ Lup…
Pictoris b through the eyes of the upgraded CRIRES+
Rico Landman, Tomas Stolker, Ignas Snellen +8
Context: High-resolution spectrographs fed by adaptive optics (AO) provide a unique opportunity to characterize directly imaged exoplanets. Observations with such instruments allow…
