The JDISC Survey: Inner Disk Chemistry of Class I/FS Disks and Tentative Evidence for Early Pebble Drift

Ke Zhang, Andrea Banzatti, Colette Salyk +22

We present the first chemical survey of Class I and Flat-Spectrum (I/FS) disks using JWST MIRI/MRS, targeting sixteen sources in the Ophiuchus star-forming region. Through empirica…

Demographics of planet-forming disks with the SKAO

Antonio Garufi, Sebastián Pérez, John D. Ilee +21

Understanding how solid material in planet-forming disks evolves from micron-sized dust to planetary cores is a central challenge in modern astrophysics. This study has advanced dr…

Substructures in Planet-Forming Disks with the SKAO

Yinhao Wu, Jessica Speedie, Sebastián Pérez +33

Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…

From Young to Older Disks: JWST/MIRI Evidence for Fading Molecular Emission and Hints for Elevated C/O in Upper Scorpius

Chengyan Xie, Ilaria Pascucci, Feng Long +23

We present JWST/MIRI spectroscopy of 14 disks in the older (~5-10 Myr) Upper Scorpius (USco) association and use slab of gas in local thermal equilibrium to infer basic gas propert…

Chemical Divergence and Water Depletion: Gas Properties of Evolved Upper Scorpius Disks Revealed by JWST/MIRI

Eshan Raul, Ke Zhang, Abygail Waggoner +25

Tracing the chemical evolution of protoplanetary disks over time requires observations of disks at different ages. However, most JWST/MIRI surveys published to date have targeted y…

Molecular Similarity and Water Diversity in Coeval Binary Disks: JWST/MIRI Observations of Sz 65 and Sz 66

Jinghuai Yao, Ke Zhang, Andrea Banzatti +10

We present JWST/MIRI Medium Resolution Spectrometer spectra of the wide-separation (projected separation au) binary protoplanetary disks Sz 65 (K7; ) and Sz…
