Till Kaeufer, Rens Waters, Danny Gasman +16
Our knowledge of the chemical composition of the gas in the inner disc of intermediate-mass young stars is limited, due to the lack of suitable instrumentation. The launch of JWST…
JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b

Hyerin Jang, Aditya M. Arabhavi, Till Kaeufer +11
Disks around very low-mass stars (VLMS) provide environments for the formation of Earth-like planets. Mid-infrared observations have revealed that these disks exhibit weak silicate…
A carbon-rich disk surrounding a planetary-mass companion
Gabriele Cugno, Sierra L. Grant
During the final assembly of gas giant planets, circumplanetary disks (CPDs) of gas and dust form due to the conservation of angular momentum, providing material to be accreted ont…
A transition from HO to CH dominated spectra with decreasing stellar luminosity
Sierra L. Grant, Milou Temmink, Ewine F. van Dishoeck +19
The chemical composition of the inner regions of disks around young stars will determine the properties of planets forming there. Many disk physical processes drive the chemical ev…
MINDS. Young binary systems with JWST/MIRI: Variable water-rich primaries and extended emission
Nicolas T. Kurtovic, Sierra L. Grant, Milou Temmink +16
As part of the JWST GTO program MINDS, we analyze the mid-infrared emission of three Class II binary systems: VW Cha, WX Cha, and RW Aur, to investigate the impact of stellar multi…
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…
MINDS: The very low-mass star and brown dwarf sample. Detections and trends in the inner disk gas
A. M. Arabhavi, I. Kamp, Th. Henning +22
Planet-forming disks around brown dwarfs and very low-mass stars (VLMS) are on average less massive and are expected to undergo faster radial solid transport than their higher mass…
MINDS. Water reservoirs of compact planet-forming dust disk: A diversity of HO distributions
Milou Temmink, Andrew D. Sellek, Danny Gasman +17
Millimetre-compact dust disks are thought to have efficient radial drift of icy dust pebbles, which has been hypothesised to produce an enhanced cold (400 K) HO reservoir i…
