MINDS: The molecule-rich disc of the Herbig star HD 35929 revealed with JWST/MIRI
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…
MINDS: The very low-mass star and brown dwarf sample II. Probing disk settling, dust properties, and dust-gas interplay with JWST/MIRI
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…
MINDS. Cha Hα 1, a brown dwarf with a hydrocarbon-rich disk
María 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…
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…
XUE 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk
Jenny Frediani, Arjan Bik, María Claudia Ramírez-Tannus +18
We investigate the James Webb Space Telescope (JWST) MIRI MRS gas molecular content of an externally irradiated Herbig disk, the F-type XUE 10 source, in the context of the eXtreme…
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…
Burned to ashes: How the thermal decomposition of refractory organics in the inner protoplanetary disc impacts the gas-phase C/O ratio
Adrien Houge, Anders Johansen, Edwin Bergin +5
The largest reservoir of carbon in protoplanetary discs is stored in refractory organics, which thermally decompose into the gas-phase at the organics line, well interior to the wa…
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…
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…
Dust processing in the terrestrial planet-forming region of the PDS 70 disk
Yao Liu, Dafa Li, Hongchi Wang +5
Dust grains in protoplanetary disks are the building blocks of planets. Investigating the dust composition and size, and their variation over time, is crucial for understanding the…
MINDS. The influence of outer dust disc structure on the volatile delivery to the inner disc
Danny Gasman, Milou Temmink, Ewine F. van Dishoeck +18
ALMA has revealed that the millimetre dust structures of protoplanetary discs are extremely diverse. It has been proposed that the strength of HO emission in the inner disc par…
