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…

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…

JWST Edge-on Disk Ice (JEDIce): Program overview and ice survey results

Jennifer B. Bergner, Nicole Arulanantham, Emmanuel Dartois +21

The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28m spectra of five disks…

HO in the terrestrial planet-forming regions of protoplanetary disks

Colette Salyk, Klaus M. Pontoppidan, Ke Zhang +12

Isotopologues play an important role in solar system cosmochemistry studies, revealing details of early planet formation physics and chemistry. Oxygen isotopes, as measured in sola…

The Flying Saucer edge-on disc's Near Infrared silhouette revealed by the JWST JEDIce program

Emmanuel Dartois, Jennifer A. Noble, Jennifer B. Bergner +17

Edge-on discs offer a unique opportunity to probe radial and vertical dust and gas distributions in the protoplanetary phase. This study aims to investigate the distribution of mic…

JWST-TST High Contrast: Medium-resolution spectroscopy reveals a carbon-rich circumplanetary disk around the young accreting exoplanet Delorme 1 AB b

Mathilde Mâlin, Kimberly Ward-Duong, Sierra L. Grant +21

Young accreting planetary-mass objects are thought to draw material from a circumplanetary disk (CPD) composed of gas and dust. While the gas within the disk is expected to dispers…
