Chemistry and Isotope Ratios of Substellar Atmospheres in the Pictoris Young Moving Group and Vicinity
Yurou Liu, Yapeng Zhang, Jerry W. Xuan +7
Measuring the chemical and isotopic compositions of gas giants and brown dwarfs provides insights into their formation pathways and birth environments. 2MASS J0249-0557 c is an L2-…
Panchromatic View of the Frigid Jovian Exoplanet COCONUTS-2 b
Matthieu Ravet, Mickaël Bonnefoy, Gaël Chauvin +24
We use a high signal-to-noise MIRI-LRS spectrum (5.45 - 11 m, R ) of COCONUTS-2~b revealing prominent molecular features of HO, CH and NH. This dataset…
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…
Chemical evolution imprints in the rare isotopes of nearby M dwarfs
Darío González Picos, Ignas Snellen, Sam de Regt
Elements heavier than hydrogen and helium, collectively termed metals, were created inside stars and dispersed through space at the final stages of stellar evolution. The relative…
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 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…
The ESO SupJup Survey II: The 12C/13C ratios of three young brown dwarfs with CRIRES
D. González Picos, I. A. G. Snellen, S. de Regt +7
Young brown dwarfs exhibit atmospheric characteristics similar to those of super-Jupiters, providing a unique opportunity to study planetary atmospheres. The ESO SupJup Survey, uti…
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…
Polarimetric differential imaging with VLT/NACO. A comprehensive PDI pipeline for NACO data (PIPPIN)
S. de Regt, C. Ginski, M. A. Kenworthy +9
The observed diversity of exoplanets can possibly be traced back to the planet formation processes. Planet-disk interactions induce sub-structures in the circumstellar disk that ca…
JWST measurements of C, O and O in the atmosphere of super-Jupiter VHS 1256 b
Siddharth Gandhi, Sam de Regt, Ignas Snellen +4
Isotope ratios have recently been measured in the atmospheres of directly-imaged and transiting exoplanets from ground-based observations. The arrival of JWST allows us to characte…
A quantitative assessment of the VO line list: Inaccuracies hamper high-resolution VO detections in exoplanet atmospheres
S. de Regt, A. Y. Kesseli, I. A. G. Snellen +2
Metal hydrides and oxides are important species in hot-Jupiters since they can affect their energy budgets and the thermal structure of their atmospheres. One such species is VO, w…
