JWST Edge-on Disk Ice (JEDIce): Vibrationally hot, rotationally cold H in the outer disk of Oph 163131 non-thermally excited by UV and cosmic rays

Korash Assani, Zhi-Yun Li, Jennifer B. Bergner +19

Constraining ionization and excitation processes in protoplanetary disks is essential for understanding the chemical structure and evolution of disk material, shaping planet format…

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…

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…

Variation of the disk thickness across ice bands: A method to determine ice abundances in highly inclined protoplanetary disks

Laurine Martinien, Gaspard Duchêne, François Ménard +6

The James Webb Space Telescope provides unprecedented information to study ices in protoplanetary disks. However, the saturation of ice bands in highly inclined disks hinders the m…

Chemical constraints on the dynamical evolution of the cold core L694

A. Taillard, V. Wakelam, P. Gratier +4

In star-forming regions, molecular cloud history and dynamics set the trend in the chemical composition. Ice formation, in particular, is affected by the evolution of physical cond…

The edge-on disk Tau042021: icy grains at high altitudes and a wind containing astronomical PAHs

E. Dartois, J. A. Noble, M. K. McClure +9

Spectra of the nearly edge-on protoplanetary disks observed with the JWST have shown ice absorption bands of varying optical depths and peculiar profiles, challenging radiative tra…

Modelling methanol and hydride formation in the JWST Ice Age era

Izaskun Jiménez-Serra, Andrés Megías, Joseph Salaris +19

(Abridged) JWST observations have measured the ice composition toward two highly-extinguished field stars in the Chamaeleon I cloud. The observed extinction excess on the long-wave…

Predicting the detectability of sulphur-bearing molecules in the solid phase with simulated spectra of JWST instruments

A. Taillard, R. Martín-Doménech, H. Carrascosa +7

To date, gas phase observations of sulphur in dense interstellar environments have only constrained the molecular carriers of 1% of its predicted cosmic abundance. An additional 5%…

JWST ice band profiles reveal mixed ice compositions in the HH 48 NE disk

Jennifer B. Bergner, J. A. Sturm, Elettra L. Piacentino +19

Planet formation is strongly influenced by the composition and distribution of volatiles within protoplanetary disks. With JWST, it is now possible to obtain direct observational c…

A JWST/MIRI analysis of the ice distribution and PAH emission in the protoplanetary disk HH 48 NE

J. A. Sturm, M. K. McClure, D. Harsono +18

Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres. How…

JWST MIRI MRS Images Disk Winds, Water, and CO in an Edge-On Protoplanetary Disk

Nicole Arulanantham, M. K. McClure, Klaus Pontoppidan +14

We present JWST MIRI MRS observations of the edge-on protoplanetary disk around the young sub-solar mass star Tau 042021, acquired as part of the Cycle 1 GO program "Mapping Inclin…

A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk

Olivier Berné, Emilie Habart, Els Peeters +143

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
