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: 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…
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…
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…
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…
