ALMA-QUARKS: Few-Thousand-Year Hatching out of "Egg": The Supersonic Breakout of a Hypercompact H II Region from Its Parental Hot Core
Siju Zhang, Guido Garay, Fengwei Xu +19
The kinematic evolution of hypercompact H II (HC H II) regions around young high-mass stars remains poorly understood due to complex interactions with parental environs. We present…
Ubiquity of Methanol and its related Chemical Segregation in Orion Starless Cores: the ALMASOP Sample
Shih-Ying Hsu, Sheng-Yuan Liu, Xunchuan Liu +8
Complex organic molecules (COMs) in starless cores provide critical insights into the early stages of star formation and prebiotic chemistry. We present a chemical survey of 16 sta…
The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). XIII. Core Mass Function, Lifetime, and Growth of Prestellar Cores
Kaho Morii, Patricio Sanhueza, Qizhou Zhang +10
The core mass function (CMF) of prestellar cores is essential for understanding the initial conditions of star and cluster formation. However, the universality of the CMF and its r…
Magnetic Fields in Massive Star-forming Regions (MagMaR). VI. Magnetic Field Dragging in the Filamentary High-mass Star-forming Region G35.20--0.74N due to Gravity
Jihye Hwang, Patricio Sanhueza, Josep Miquel Girart +27
We investigate the magnetic field orientation and strength in the massive star-forming region G35.20-0.74N (G35), using polarized dust emission data obtained with the Atacama Large…
A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…
Detection of a septuple stellar system in formation via disk fragmentation
Shanghuo Li, Henrik Beuther, André Oliva +15
Stellar multiple systems play a pivotal role in cluster dynamics and stellar evolution, leading to intense astronomical phenomena like X-ray binaries, gamma-ray bursts, Type Ia sup…
Dense Molecular Ring-like structure in gaseous CO depletion region G34.74-0.12
Shuting Lin, Siyi Feng, Fengwei Xu +14
We report the discovery of a dense molecular ring-like structure in a dense (10 cm), cold (pc-scale CO depletion at a factor of 5), and young (10 year) star-forming…
Unveiling Central ortho-H2D+ Depletion at Sub-kau Scales in Prestellar Core G205.46-14.56M3: The First Interferometric Evidence and Implications for Deuterium Chemistry
Sheng-Jun Lin, Sheng-Yuan Liu, Dipen Sahu +8
Prestellar cores represent the initial conditions of star formation, but heavy molecules such as CO are strongly depleted in their cold, dense interiors, limiting the ability to pr…
Impact of gravity on changing magnetic field orientations in a sample of massive protostellar clusters observed with ALMA
Qizhou Zhang, Junhao Liu, Lingzhen Zeng +12
The magnetic field is integral to our understanding of the formation and dynamical evolution of molecular clouds and star formation within. We present a polarimetric survey of 17 m…
Massive extended streamers feed high-mass young stars
Fernando A. Olguin, Patricio Sanhueza, Adam Ginsburg +13
Stars are born in a variety of environments that determine how they gather gas to achieve their final masses. It is generally believed that disks are ubiquitous around protostars a…
The ALMA-QUARKS Survey: III. Clump-to-core fragmentation and search for high-mass starless cores
Dongting Yang, Hong-Li Liu, Tie Liu +43
The Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures (QUARKS) survey observed 139 infrared-bright (IR-bright) massive proto…

Interstellar complex organic molecules (COMs) in solar-like young stellar objects (YSOs), particularly within protostellar disks, are of significant interest due to their potential…
ALMASOP. Detection of Turbulence-induced Mass Assembly Shocks in Starless Cores
Shih-Ying Hsu, Sheng-Yuan Liu, Xunchuan Liu +8
Star formation is a series of mass assembly processes and starless cores, those cold and dense condensations in molecular clouds, play a pivotal role as initial seeds of stars. Wit…
