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…
JOYS: Launching and destruction of dust in protostellar jets. The case of BHR71-IRS1 with JWST/MIRI
Åukasz Tychoniec, Logan Francis, Maria Gabriela Navarro +24
Protostellar winds can theoretically lift solids from the planet-forming disks, but direct evidence for launched dust has been scarce so far. Numerous atomic lines that are unique…
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 disk…
Probing Dust in the MWC 480 Disk from Millimeter to Centimeter Wavelengths
Yangfan Shi, Feng Long, Enrique MacÃas +12
We present deep, high-resolution (100 mas) Karl G. Jansky Very Large Array (VLA) Ka-band (9.1 mm) observations of the disk around MWC 480, and infer dust properties through a…
Characterizing the physical and chemical properties of the Class I protostellar system Oph-IRS 44. Binarity, infalling streamers, and accretion shocks
E. Artur de la Villarmois, V. V. Guzmán, M. L. van Gelder +5
(Abridged) In the low-mass star formation process, theoretical models predict that material from the infalling envelope could be shocked as it encounters the outer regions of the d…
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…
