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…
