Carlos E. Romero-Mirza, Karin I. Öberg, Andrea Banzatti +24
We present MIRI MRS observations of the large, multi-gapped protoplanetary disk around the T-Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9 to 25…
Water-Rich Disks around Late M-stars Unveiled: Exploring the Remarkable Case of Sz114
Chengyan Xie, Ilaria Pascucci, Feng Long +18
We present an analysis of the JDISC JWST/MIRI-MRS spectrum of Sz~114, an accreting M5 star surrounded by a large dust disk with a shallow gap at au. The spectrum is molec…
High-contrast JWST-MIRI spectroscopy of planet-forming disks for the JDISC Survey
Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +26
The JWST Disk Infrared Spectral Chemistry Survey (JDISCS) aims to understand the evolution of the chemistry of inner protoplanetary disks using the Mid-InfraRed Instrument (MIRI) o…
UV-Optical Emission of AB Aur b is Consistent with Scattered Stellar Light
Yifan Zhou, Brendan P. Bowler, Haifeng Yang +12
The proposed protoplanet AB Aur b is a spatially concentrated emission source imaged in the mm-wavelength disk gap of the Herbig Ae/Be star AB Aur. Its near-infrared spectrum and a…
MAPS: Constraining Serendipitous Time Variability in Protoplanetary Disk Molecular Ion Emission

Theoretical models and observations suggest that the abundances of molecular ions in protoplanetary disks should be highly sensitive to the variable ionization conditions set by th…
The Effect of Dust Evolution and Traps on Inner Disk Water Enrichment
Anusha Kalyaan, Paola Pinilla, Sebastiaan Krijt +6
Substructures in protoplanetary disks can act as dust traps that shape the radial distribution of pebbles. By blocking the passage of pebbles, the presence of gaps in disks may hav…
JWST reveals excess cool water near the snowline in compact disks, consistent with pebble drift
Andrea Banzatti, Klaus M. Pontoppidan, John Carr +19
Previous analyses of mid-infrared water spectra from young protoplanetary disks observed with the Spitzer-IRS found an anti-correlation between water luminosity and the millimeter…
