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…
