![Overview of the MIRI-MRS spectra of the three T Tauri disks along with ALMA views of their dust emission for illustrative purposes. The mid-IR emission is dominated by a dust continuum with particularly flat silicate features in DL Tau and V1094 Sco, revealing large micron-sized grains with a prominent silica feature. The 13-16 µm region shows a wealth of molecular features with a prominent C2H2, HCN, and CO2 features outlined in Fig. 2. In addition the pure rotational lines of H2 and the Ne [II] line are seen in all three disks. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/04/MINDS.png?resize=1200%2C720&ssl=1)
(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 cases of […]

JWST/MIRI Detection Of A Carbon-rich Chemistry In A Solar Nebula Analog
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their hotter, more massive […]
