Optical depth maps of the near-IR H2O, CO2, and CO ice features in the disk sample, calculated for pixels with a >3σ detection across the ice band. For clarity, the color map within each panel is individually normalized (i.e., divided by the maximum per-pixel optical depth for a given ice band in a given disk). The maximum optical depths are indicated in the bottom left of each panel. Dotted grey lines represent the 3σ contour of the near-IR continuum maps shown in Figure 1. Horizontal bars represent a linear scale of 100 au. -- astro-ph.EP

JWST Edge-on Disk Ice (JEDIce): Program Overview And Ice Survey Results

by Keith CowingMarch 22, 2026March 22, 2026

The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28μm spectra of five disks obtained as part of […]
