MINDS: Complementary inclinations in the binary system HK Tau reveal gas- and ice-phase chemistry
Alice Somigliana, Giulia Perotti, Nicolás T. Kurtovic +18
[Abridged] HK Tau is a roughly equal mass pre-main sequence binary system consisting of a low-inclination primary (57 deg) and an edge-on (83 deg) secondary. We present JWST/MIRI o…
MINDS survey of silicates in T Tauri disks: Correlation between dust and gas

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…
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…
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…
MINDS: The very low-mass star and brown dwarf sample -- Hidden water in carbon-dominated protoplanetary disks
Aditya M. Arabhavi, Inga Kamp, Ewine F. van Dishoeck +21
Infrared observations of the inner disks around very low-mass stars (VLMS, 0.3) have revealed a carbon-rich gas composition in the terrestrial planet-forming region…
