A vision for ground-based astronomy beyond the 2030s: How to build ESO's next big telescope sustainably
Laurane Fréour, Mathilde Bouvier, Tony Mroczkowski +8
Astronomy is the study of the Universe and all the objects that it comprises. Our attention is therefore usually focused beyond Earth, home to the only form of life known today. Ho…
Interferometric Detection and Orbit Modeling of the Subcomponent in the Hot-dust System Tuc A: A Low-mass Star on an Eccentric Orbit in a Hierarchical-quintuple System
T. A. Stuber, A. Mérand, F. Kirchschlager +19
The system Tuc A is part of a hierarchical-quintuple system and is a prime target for studies of hot-exozodiacal dust, because a time-variable near-infrared excess has been det…
Evidence for SiO cloud nucleation in the rogue planet PSO J318
P. Mollière, H. Kühnle, E. C. Matthews +25
Silicate clouds are known to significantly impact the spectra of late L-type brown dwarfs, with observable absorption features at ~ 10 micron. JWST has reopened our window to the m…
MINDS: Detection of an inner gas disk caused by evaporating bodies around HD 172555
M. Samland, T. Henning, A. Caratti o Garatti +23
Mechanisms such as collisions of rocky bodies or cometary activity give rise to dusty debris disks. Debris disks trace the leftover building blocks of planets, and thus also planet…
Panchromatic characterization of the Y0 brown dwarf WISEP J173835.52+273258.9 using JWST/MIRI
Malavika Vasist, Paul Mollire, Helena Kühnle +9
Cold brown dwarf atmospheres are good training grounds for analyzing temperate giant planets. WISEP J173835.52+273258.9 (WISE 1738) is an isolated Y0 brown dwarf with a temperature…
JWST/MIRI observations of the young TWA 27 system: hydrocarbon disk chemistry, silicate clouds, evidence for a CPD
P. Patapis, M. Morales-Calderón, A. M. Arabhavi +39
The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) enables the characterisation of young self-luminous gas giants at previously inaccessible wavelengths, r…
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…
Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam
Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39
The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…
MIRI-JWST mid-infrared direct imaging of the debris disk of HD106906
Daniel Rouan, Anthony Boccaletti, Clément Perrot +20
We report MIRI-JWST coronagraphic observations at 11.3 and 15.5 mic of the debris disk around the young star HD 106906. The observations were made to characterize the structure, te…
HCN and C2H2 in the atmosphere of a T8.5+T9 brown dwarf binary
Elisabeth C. Matthews, Paul Mollière, Helena Kühnle +22
T-type brown dwarfs present an opportunity to explore atmospheres teeming with molecules such as H2O, CH4 and NH3, which exhibit a wealth of absorption features in the mid-infrared…
First unambiguous detection of ammonia in the atmosphere of a planetary mass companion with JWST/MIRI coronagraphs
Mathilde Mâlin, Anthony Boccaletti, Clément Perrot +28
The newly accessible mid-infrared (MIR) window offered by the James Webb Space Telescope (JWST) for exoplanet imaging is expected to provide valuable information to characterize th…
