Magnetic Fields and Asymmetric Accretion in the Class 0 Protostellar System L1527 IRS
Hanju Nam, Woojin Kwon, Youngwoo Choi +2
Magnetic fields play a crucial role in regulating the collapse of dense molecular clouds, shaping the early stages of protostellar evolution. We present polarization observations i…
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…
HOPS-288: A Laboratory for Complex Organics in Proto-multiple Systems
Shih-Ying Hsu, Nadia M. Murillo, Chin-Fei Lee +21
Complex organic molecules (COMs) in young stellar objects (YSOs) have attracted significant attention in recent years due to their potential connection to pre-biotic chemistry and…
A Bridge between Young Stars Formed by Gravitational Interaction
Youngwoo Choi, Woojin Kwon, Leslie W. Looney +1
The majority of stars are born in clustered environments. In these environments, close encounters between young stars with planet-forming disks are expected to occur frequently. Ho…
Multi-band ALMA Polarization Observations of BHB07-11 Reveal Aligned Dust Grains in Complex Spiral Arm Structures
Austen Fourkas, Leslie W. Looney, Zhe-Yu Daniel Lin +8
Polarization-mode observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are powerful tools for studying the dust grain populations in circumstellar disks. Many…
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…
The Hourglass-shaped Magnetic Fields and Dust Filaments in the HH 211 Protostellar Envelope
Youngwoo Choi, Woojin Kwon, Leslie W. Looney +4
Magnetic fields influence the structure and evolution of protostellar systems, thus understanding their role is essential for probing the earliest stages of star formation. We pres…
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…
L1448 IRS3B: Dust Polarization Aligned with Spiral Features, Tracing Gas Flows
Leslie W. Looney, Zhe-Yu Daniel Lin, Zhi-Yun Li +11
Circumstellar disk dust polarization in the (sub)millimeter is, for the most part, not from dust grain alignment with magnetic fields but rather indicative of a combination of dust…
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…
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…
Early Planet Formation in Embedded Disks (eDisk) X: Compact Disks, Extended Infall, and a Fossil Outburst in the Class I Oph IRS43 Binary
Suchitra Narayanan, Jonathan P. Williams, John J. Tobin +17
We present the first results from the Early Planet Formation in Embedded Disks (eDisk) ALMA Large Program toward Oph IRS43, a binary system of solar mass protostars. The 1.3 mm dus…
Early Planet Formation in Embedded Disks (eDisk) XII: Accretion streamers, protoplanetary disk, and outflow in the Class I source Oph IRS63
Christian Flores, Nagayoshi Ohashi, John J. Tobin +25
We present ALMA observations of the Class I source Oph IRS63 in the context of the Early Planet Formation in Embedded Disks (eDisk) large program. Our ALMA observations of Oph IRS6…
