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 IX: Isotopic evidence of a recent formation for Luhman 16AB

S. de Regt, I. A. G. Snellen, D. González Picos +8

The distinct formation pathways of directly-imaged exoplanets and isolated brown dwarfs might leave imprints in the inherited elemental and isotopic abundances, but such measuremen…

Disentangling disc and atmospheric signatures of young brown dwarfs with JWST/NIRSpec

D. González Picos, S. de Regt, S. Gandhi +2

Young brown dwarfs serve as analogues of giant planets and provide benchmarks for atmospheric and formation models. JWST has enabled access to near-infrared spectra of brown dwarfs…

The ESO SupJup Survey VIII. Chemical fingerprints of young L dwarf twins

N. Grasser, I. A. G. Snellen, S. de Regt +8

The potentially distinct formation pathways of exoplanets and brown dwarfs may be imprinted in their elemental and isotopic ratios. This work is part of the ESO SupJup Survey, whic…

The ESO SupJup Survey VII: Clouds and line asymmetries in CRIRES J-band spectra of the Luhman 16 binary

S. de Regt, I. A. G. Snellen, N. F. Allard +8

Brown dwarfs at the L-T transition likely experience an inhomogeneous clearing of the clouds in their atmospheres. The resulting surface of thin and thick cloudy patches has been p…

The ESO SupJup Survey V: Exploring Atmospheric Variability and Orbit of the Super-Jupiter AB Pictoris b with CRIRES+

Siddharth Gandhi, Sam de Regt, Ignas Snellen +12

A growing number of directly-imaged companions have been recently characterised, with robust constraints on carbon-to-oxygen ratios and even isotopic ratios. Many companions and is…

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…

The ESO SupJup Survey I: Chemical and isotopic characterisation of the late L-dwarf DENIS J0255-4700 with CRIRES

S. de Regt, S. Gandhi, I. A. G. Snellen +9

It has been proposed that the distinct formation and evolution of exoplanets and brown dwarfs may affect the chemical and isotopic content of their atmospheres. Recent work has ind…

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…
