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…
Compact Hydrogen Sulfide Emission Indicates Sulfur-bearing Ice Sublimation in the Inner Disk of HD 163296
Yoshihide Yamato, Yuri Aikawa, Kenji Furuya +8
The sulfur chemistry in protoplanetary disks directly affects the composition and potential habitability of nascent planets, but its volatile inventory remains highly uncertain. He…
Tracing Pebble Drift History in Two Protoplanetary Disks with CO Enhancement
Tayt Armitage, Joe Williams, Ke Zhang +15
Pebble drift is an important mechanism for supplying the materials needed to build planets in the inner region of protoplanetary disks. Thus, constraining pebble drift's timescales…
Protoplanetary disk cavities with JWST-MIRI: a dichotomy in molecular emission
Patrick Mallaney, Andrea Banzatti, Colette Salyk +24
The evolution of planet-forming regions in protoplanetary disks is of fundamental importance to understanding planet formation. Disks with a central deficit in dust emission, a "ca…
Cosmic cascades: How disk substructure regulates the flow of water to inner planetary systems
Sebastiaan Krijt, Andrea Banzatti, Ke Zhang +17
The influx of icy pebbles to the inner regions of protoplanetary disks constitutes a fundamental ingredient in most planet formation theories. The observational determination of th…
Grand Design Spiral Arms in the Compact, Embedded Protoplanetary Disk of Haro 6-13
Jane Huang, Masataka Aizawa, Jaehan Bae +6
Millimeter continuum spiral arms have so far only been detected in a handful of protoplanetary disks, and thus we have a limited understanding of the circumstances in which they ca…
