Nascent Embedded-protostar Survey in Taurus (NEST) II: Measuring Dust Mass, Disk Size, and Gas Mass
Noshin Yesmin, Patrick Sheehan, John Tobin +6
Envelope-embedded protostellar disks represent the earliest stage of protoplanetary disk evolution, but their masses and sizes are difficult to measure because disk emission is ent…
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…
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…
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…

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…
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…
Sub-Millimeter Variability in the Envelope & Warped Protostellar Disk of the Class 0 Protostar HOPS 358
Patrick D. Sheehan, Doug Johnstone, Carlos Contreras Peña +7
The JCMT Transient Survey recently discovered that the Class 0 protostar HOPS 358 decreased in 350 GHz continuum brightness by % over the course of four years before bright…
An embedded Disk (eDisk) in the IceAge: Investigating the jet and outflow from CED 110 IRS4
Mayank Narang, Nagayoshi Ohashi, John J. Tobin +3
We present a comprehensive study of the large-scale structure, jet and outflow morphology, and kinematics of the Class 0/I protostellar binary Ced 110 IRS4, using JWST NIRCam (F150…
Early Grain Growth in the Young Protostellar Disk HH 212 Supported by Dust Self-Scattering Modeling
Ying-Chi Hu, Chin-Fei Lee, Zhe-Yu Daniel Lin +3
Grain growth in disks around young stars plays a crucial role in the formation of planets. Early grain growth has been suggested in the HH 212 protostellar disk by previous polariz…
JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS370 -- Evidence for an Opacity Hole and Thermal Processing of Ices
Himanshu Tyagi, Manoj P., Mayank Narang +35
The composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during th…
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

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…
An Observational View of Structure in Protostellar Systems
John J. Tobin, Patrick D. Sheehan
The envelopes and disks that surround protostars reflect the initial conditions of star and planet formation and govern the assembly of stellar masses. Characterizing these structu…
