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…
