The chemical diversity of giant-planet nurseries as revealed by ALMA
Alice S. Booth, Jenny Calahan, Milou Temmink +9
With the giant exoplanet occurrence rate peaking around stars of 1.5-2 solar masses, there is strong motivation to characterize the disks that set their formation conditions. Obser…
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…
Observational evidence for a possible link between PAH emission and dust trap locations in protoplanetary disks
Nienke van der Marel, Niels F. W. Ligterink, Ryan van der Werf +4
Polycyclic Aromatic Hydrocarbons (PAHs) are commonly detected in protoplanetary disks, but it is unclear what causes the wide range of intensities across the samples. In this work,…
Understanding JWST water spectra: what can thermochemical models tell us about the (cold) water in protoplanetary disks?
Marissa Vlasblom, Milou Temmink, Andrew D. Sellek +1
(Abridged) Rotational HO spectra as observed with JWST/MIRI provide a good probe of the temperature and column density structure of the inner disk. HO emission can also be…
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…
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…
Ice sublimation in the dynamic HD 100453 disk reveals a rich reservoir of inherited complex organics
Alice S. Booth, Lisa Wölfer, Milou Temmink +7
Protoplanetary disks around luminous young A-type stars are prime observational laboratories to determine the abundances of complex organic molecules (COMs) present during planet f…
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…
ALMA reveals thermal and non-thermal desorption of methanol ice in the HD 100546 protoplanetary disk
Lucy Evans, Alice S. Booth, Catherine Walsh +8
Methanol (CHOH) and formaldehyde (HCO) are chemically coupled organic molecules proposed to act as an intermediate step between simple molecules and more complex prebiotic…
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…
