Multi-modal atmospheric characterization of Pictoris b: Adding high-resolution continuum spectra from GRAVITY

M. Ravet, M. Bonnefoy, G. Chauvin +24

We present the first VLTI/GRAVITY observations at R of Pic b. These four high S/N (20) K-band spectra conserve both the pseudo-continuum and molecular absorp…

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…
