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…
Chemistry and IR emission of acetylene in planet-forming regions of T Tauri disks. Impact of elemental abundances and dust properties
Pacôme Estève, Benoît Tabone, Emilie Habart +5
(Abridged) We aim to explore the parameters that influence the mid-infrared emission of CH and HO, and if the spread observed in / is tr…
MINDS survey of silicates in T Tauri disks: Correlation between dust and gas
J. Varga, Th. Henning, L. B. F. M. Waters +20
Context. Silicates are key constituents of planet-forming disks and major building blocks of rocky planets. Mid-infrared spectral features of micron-sized silicate grains trace gra…
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…
Detecting nitrogen-carriers in the inner regions of protoplanetary disks
Marissa Vlasblom, Aditya M. Arabhavi, Niels de Klerk +3
Nitrogen is a key element for building habitable worlds, yet only a small fraction of the available N-budget of planet-forming disks has been detected. In particular, the lack of a…
Molecular diagnostics for the mid-infrared emission of planet-forming disks. Carbon and oxygen elemental abundances
Aditya M. Arabhavi, Inga Kamp, Ewine F. van Dishoeck +8
Mid-infrared observations of planet-forming disks reveal a wide diversity in molecular spectra. Carbon and oxygen abundances play a central role in setting the chemical environment…
