Probing Planet Formation with JWST Spectroscopy of IC348: Sustained Diversity but Limited Chemical Evolution and Pebble Drift

John S. Carr, Joan R. Najita

Inner disk chemistry offers a valuable window onto disk evolution and planet formation. Key planet formation processes, including pebble drift, planetesimal and planet formation, d…

JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation

María José Colmenares, Edwin A. Bergin, Ke Zhang +27

We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum (1 Myr old) source, to investigate the chemical composition and dynamical origin of i…

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 JDISC Survey: Linking the Physics and Chemistry of Inner and Outer Protoplanetary Disk Zones

Nicole Arulanantham, Colette Salyk, Klaus Pontoppidan +20

Mid-infrared spectroscopy of protoplanetary disks provides a chemical inventory of gas within a few au, where planets are readily detected around older stars. With the JWST Disk In…

Emission from multiple molecular isotopologues in a high-inclination protoplanetary disk

Colette Salyk, Klaus M. Pontoppidan, Andrea Banzatti +7

We present a MIRI-MRS spectrum of the high-inclination protoplanetary disk around the solar-mass (K0) star MY Lup, obtained as part of the JWST Disk Infrared Spectral Chemistry Sur…

Water in protoplanetary disks with JWST-MIRI: spectral excitation atlas and radial distribution from temperature diagnostic diagrams and Doppler mapping

Andrea Banzatti, Colette Salyk, Klaus M. Pontoppidan +19

This work aims at providing fundamental general tools for the analysis of water spectra as observed in protoplanetary disks with JWST-MIRI. We analyze 25 high-quality spectra from…

Spectroastrometric Survey of Protoplanetary Disks with Inner Dust Cavities

Stanley K. Jensen, Sean D. Brittain, Andrea Banzatti +6

We present high-resolution spectra and spectroastrometric (SA) measurements of fundamental rovibrational CO emission from nine nearby (300 pc) protoplanetary disks where…

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…

The Atomic and Molecular Content of Disks Around Very Low-mass Stars and Brown Dwarfs

Ilaria Pascucci, Greg Herczeg, John Carr +1

There is growing observational evidence that disk evolution is stellar-mass dependent. Here, we show that these dependencies extend to the atomic and molecular content of disk atmo…

A Spitzer Survey of Mid-Infrared Molecular Emission from Protoplanetary Disks II: Correlations and LTE Models

C. Salyk, K. M. Pontoppidan, G. A. Blake +2

We present an analysis of Spitzer-IRS observations of H2O, OH, HCN, C2H2, and CO2 emission, and Keck-NIRSPEC observations of CO emission, from a diverse sample of T Tauri and Herbi…
