Early Planet Formation in Embedded Disks (eDisk). XIX. Structures of molecular outflows
Anton Feeney-Johansson, Yuri Aikawa, Shigehisa Takakuwa +13
As part of the ALMA Large Program "Early Planet Formation in Embedded Disks" (eDisk), 12CO (2 - 1) was observed towards 19 nearby low-mass protostars. Of these objects, 15 sources…
Protostellar Outflows Shed Light on the Dominant Close Companion Star Formation Pathways
Ryan Sponzilli, Leslie Looney, John J. Tobin +11
Understanding the formation pathway for close-companion protostars is central to unraveling the processes that govern stellar multiplicity and very early star formation. We analyze…
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) XIII: Aligned Disks with Non-Settled Dust Around the Newly Resolved Class 0 Protobinary R CrA IRAS 32
Frankie J. Encalada, Leslie W. Looney, Shigehisa Takakuwa +19
Young protostellar binary systems, with expected ages less than 10 years, are little modified since birth, providing key clues to binary formation and evolution. We prese…
