Early Planet Formation in Embedded Disks (eDisk). XXIV: Systematic Investigation of Disk Structures based on Visibility Analysis
Mayank Narang, Jerry Xu, Leslie W. Looney +11
The dust continuum emission from young protostellar disks encodes key information about their mass distribution and early evolution, yet uniform high-resolution comparative studies…
Early Planet Formation in Embedded Disks (eDisk) XXII: Keplerian disk, disk structures and jets/outflows in the Class 0 protostar IRAS 04166+2706
Nguyen Thi Phuong, Chang Won Lee, John J. Tobin +20
We present ALMA observations of the Class 0 protostar IRAS 04166+2706, obtained as part of the ALMA large program Early Planet Formation in Embedded Disks (eDisk). These observatio…
Early Planet Formation in Embedded Disks (eDisk) XXI: Limited role of streamers in mass supply to the disk in the Class 0 protostar IRAS 16544-1604
Miyu Kido, Hsi-Wei Yen, Jinshi Sai +17
Asymmetric and narrow infalling structures, often called streamers, have been observed in several Class 0/I protostars, which is not expected in the classical star formation pictur…
Early Planet Formation in Embedded Disks (eDisk) XVI: An asymmetric dust disk driving a multi-component molecular outflow in the young Class 0 protostar GSS30 IRS3
Alejandro Santamaria-Miranda, Itziar de Gregorio-Monsalvo, Nagayoshi Ohashi +17
We present the results of the ALMA Large Program Early Planet Formation in Embedded disks observations of the Class 0 protostar GSS30 IRS3. Our observations included 1.3 mm continu…
Early Planet Formation in Embedded Disks (eDisk) XV: Influence of Magnetic Field Morphology in Dense Cores on Sizes of Protostellar Disks
Hsi-Wei Yen, Jonathan P. Williams, Jinshi Sai +15
The magnetic field of a molecular cloud core may play a role in the formation of circumstellar disks in the core. We present magnetic field morphologies in protostellar cores of 16…
Direct-imaging Discovery of a Substellar Companion Orbiting the Accelerating Variable Star, HIP 39017
Taylor L. Tobin, Thayne Currie, Yiting Li +23
We present the direct-imaging discovery of a substellar companion (a massive planet or low-mass brown dwarf) to the young, Doradus-type variable star, HIP 39017 (HD 65526). Th…
