Temperature structures of embedded disks: young disks in Taurus are warm

MLR Van't Hoff, D Harsono, JJ Tobin… - The Astrophysical …, 2020 - iopscience.iop.org
The chemical composition of gas and ice in disks around young stars sets the bulk
composition of planets. In contrast to protoplanetary disks (Class II), young disks that are still …
