Azimuthal molecular variations in the AB Aur planet-forming disk

Haochang Jiang, Dmitry Semenov, Myriam Benisty +5

Late infall episodes are emerging as an important driver of disk evolution. Observed as filamentary streamers in molecular lines and scattered light, such accretion perturbs disk s…

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…

The panchromatic JWST dayside spectrum of WASP-121 b reveals a refractory-rich formation

K. Angelique Kahle, Paul Mollière, Laura Kreidberg +16

One path to understand how planets form is to link their present-day atmospheric composition to predictions from planet formation models. For the hottest planets, the abundances of…

MINDS: Intertwined evolution of dust and gas in large planet-forming disks. A diversity driven by halted pebble drift?

Benoît Tabone, Milou Temmink, Laurens B. F. M. Waters +25

(Abridged) We aim to investigate the inner regions of large and massive disks orbiting T Tauri stars, thought to be progenitors of systems with wide-orbit planets and possible case…

JWST Edge-on Disk Ice (JEDIce): Program overview and ice survey results

Jennifer B. Bergner, Nicole Arulanantham, Emmanuel Dartois +21

The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28m spectra of five disks…

Changing disc compositions via internal photoevaporation II: M dwarf systems

Julia Lena Lienert, Bertram Bitsch, Thomas Henning

The chemical evolution of the inner regions of protoplanetary discs is a complex process. Several factors influence it, one being the inward drift and evaporation of volatile-rich…

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…

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…

Changing disc compositions via internal photoevaporation I: Solar-mass stars

Julia Lena Lienert, Bertram Bitsch, Thomas Henning

The chemical evolution of protoplanetary discs is not fully understood, several factors influence the final distribution of disc material. One such factor are inward drifting and e…

Close-in ice lines and the super-stellar C/O ratio in discs around very low-mass stars

J. Mah, B. Bitsch, I. Pascucci +1

The origin of the elevated C/O ratios in discs around late M dwarfs compared to discs around solar-type stars is not well understood. Here we endeavour to reproduce the observed di…
