| 概要 | Abstract
Constraining the physical and chemical structure of young embedded disks is crucial for understanding the earliest stages of planet formation. As part of the Early Planet Formation in Embedded Disks Atacama Large Millimeter/submillimeter Array Large Program, we present high spatial resolution (∼0.1 or ~15 au) observations of the 1.3 mm continuum and 13CO J = 2-1, C18O J = 2-1, and SO JN = 65-54 molecular lines toward the disk around the Class I protostar L1489 IRS. The continuum emission shows a ring-like structure at 56 au from the central protostar and tenuous, optically thin emission extending beyond -300 au. The 13CO emission traces the warm disk surface, while the C18O emission originates from near the disk midplane. |
