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-…
pyROX: Rapid Opacity X-sections
Sam de Regt, Siddharth Gandhi, Louis Siebenaler +1
In recent years, significant advances have been made in exoplanet and brown dwarf observations. By using state-of-the-art models, astronomers can determine properties of their atmo…
Chemical evolution imprints in the rare isotopes of nearby M dwarfs
DarÃo 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 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…
