Modelling the Break in the Specific Angular Momentum within the Envelope-Disk Transition Zone
Indrani Das, Shantanu Basu, Nagayoshi Ohashi +2
The observations of protostellar systems show a transition in the radial profile of specific angular momentum (and rotational velocity), evolving from ($v_ϕ\s…
Investigating the Nested Structure of the Outflow from the Low Luminosity Protostar IRAS 16253-2429 using JWST and ALMA
Mayank Narang, Himanshu Tyagi, Nagayoshi Ohashi +37
Understanding the earliest stage of star and planet formation requires detailed observations to address the connection and interplay between the accretion, outflow and disk evoluti…
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) 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…
