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…

MINDS: Complementary inclinations in the binary system HK Tau reveal gas- and ice-phase chemistry

Alice Somigliana, Giulia Perotti, Nicolás T. Kurtovic +18

[Abridged] HK Tau is a roughly equal mass pre-main sequence binary system consisting of a low-inclination primary (57 deg) and an edge-on (83 deg) secondary. We present JWST/MIRI o…

JWST-DECO: The Impact of Accretion on Mid-Infrared Observable Water in Planet-forming Disks

Jenny K. Calahan, Tarisai Dziire, Karin Öberg +13

The inner few au of a protoplanetary disk hosts the majority of observed exoplanets and is the primary planet-forming zone of the disk. The mid-IR spectra of disks, with its rich f…

Characterizing the Extended Molecular Hydrogen Winds in Protoplanetary Disks from the JWST Disk Infrared Spectroscopic Chemistry Survey

Mayank Narang, Klaus M. Pontoppidan, Colette Salyk +14

We present a comprehensive analysis of extended H emission from 34 protoplanetary disks observed with the JWST Disk Infrared Spectroscopic Chemistry Survey (JDISCS), supplement…

MINDS: Intertwined evolution of dust and gas in large planet-forming disks. A diversity driven by halted pebble drift?

Benoît Tabone, Milou Temmink, Laurens B. F. M. Waters +25

(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 case…
