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…
Pristine ices in a planet-forming disk revealed by heavy water
Margot Leemker, John J. Tobin, Stefano Facchini +4
Water is essential to our understanding of the planet-formation process and habitability on Earth. Although trace amounts of water are seen across all phases of star and planet for…
Early Planet Formation in Embedded Disks (eDisk). XX. Constraining the Chemical Tracers of Young Protostellar Sources
Rajeeb Sharma, Jes K. Jørgensen, Merel L. R. van 't Hoff +12
Recent studies indicate that the formation of planets in protoplanetary disks begins early in the embedded Class 0/I phases of protostellar evolution. The physical and chemical mak…
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…
First results from ALPPS: a sub-Alfvénic streamer in SVS13A
P. C. Cortes, J. E. Pineda, T. -H. Hsieh +22
We present the first results from the ALMA Perseus Polarization Survey (ALPPS), focusing on the magnetic field in the SVS13A circumbinary disk. The dataset includes full-Stokes dus…
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) XVII: A Compact but Structured Keplerian Disk and Large-scale Streamers Revealed in the Class I Protostellar System IRAS 04169+2702
Ilseung Han, Woojin Kwon, Yusuke Aso +22
We present high-resolution (0.05"; 8 au) dust continuum and molecular line observations toward the Class I protostellar system IRAS 04169+2702 in the Taurus B213 region, as p…
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…
The evolution of the flux-size relationship in protoplanetary discs by viscous evolution and radial pebble drift
Johan Appelgren, Anders Johansen, Michiel Lambrechts +4
In this paper we study the evolution of radiative fluxes, flux radii and observable dust masses in protoplanetary discs, in order to understand how these depend on the angular mome…
