The environments forming stellar and planetary systems
Michael Kuffmeier, Jaime E. Pineda, Peter Schilke +29
How does a star's birth environment set the mass, angular momentum and chemical complexity delivered to its planet-forming disk, and thereby whether it builds planets, brown dwarfs…
Early Planet Formation in Embedded Disks (eDisk). XXV. Inclination-Induced Minor-Axis Brightness Asymmetries Reveal Limited Dust Settling in Embedded Protostellar Disks
Sidhant Kumar Suar, Zhe-Yu Daniel Lin, Zhi-Yun Li +9
How and when dust settles in young protostellar disks is a key open question for the dust concentration needed to form planetesimals and, ultimately, planets. However, directly mea…
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…

Sanemichi Z. Takahashi, Shigehisa Takakuwa, Ryosuke Nakanishi +11
We performed numerical simulations along with radiative transfer calculations to reproduce an intriguing asymmetric shoulder feature in the dust-continuum emission of the protostel…
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…

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…
EPISODE III: The Nested Jet/Outflow Morphology of EC 53 Revealed by JWST and ALMA
Seonjae Lee, Jeong-Eun Lee, Chul-Hwan Kim +8
We present an extensive study of the structure and kinematics of the jet and outflow of EC 53, a Class I protostar with a quasi-periodic variability, using combined James Webb Spac…

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…
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 Origins & Reservoirs of Exocomets
Michele Bannister, Susanne Pfalzner, Tim Pearce +11
Small bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation…
