Detection of CO, CO, and HO in the atmosphere of the warm sub-Saturn HAT-P-12b
N. Crouzet, B. Edwards, T. Konings +29
The chemical composition of warm gas giant exoplanet atmospheres (with Teq < 1000 K) is not well known due to the lack of observational constraints. HAT-P-12 b is a warm, sub-Satur…
MINDS. Anatomy of a water-rich, inclined, brown dwarf disk: lack of abundant hydrocarbons
Giulia Perotti, Nicolás T. Kurtovic, Thomas Henning +23
2MASS J04381486+2611399 (or J0438) is one of the few young brown dwarfs (BD) with a highly inclined () disk. Here we report results from JWST-MIRI MRS, HST-ACS a…
The gas streamer G1-2-3 in the Galactic Center
S. Gillessen, F. Eisenhauer, J. Cuadra +61
The black hole in the Galactic Center, Sgr A*, is prototypical for ultra-low-fed galactic nuclei. The discovery of a hand-full of gas clumps in the realm of a few Earth masses in i…
SO2, silicate clouds, but no CH4 detected in a warm Neptune
Achrene Dyrek, Michiel Min, Leen Decin +44
WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…
Robust Data Interpretation for Perturbed Nulling Interferometers via Proper Handling of Correlated Errors
Philipp A. Huber, Felix A. Dannert, Romain Laugier +4
The detection and atmospheric characterization of potentially habitable, temperate terrestrial exoplanets using a space-based mid-infrared nulling interferometer is a major goal of…
MINDS. Cha Hα 1, a brown dwarf with a hydrocarbon-rich disk
MarÃa Morales-Calderón, Hyerin Jang, Aditya M. Arabhavi +23
Context. Recent JWST observations have shown that brown dwarfs (BD) are chemically rich, offering valuable insights into giant planet formation. Aims. As part of the MIRI mid-INfra…
