Millimeter/submillimeter variability is often attributed to dynamical disk-mediated accretion, yet detection is limited to low-mass protostars in nearby clouds. Recent observations…
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

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…
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…
ALMASOP. A Rotating Feature Rich in Complex Organic Molecules in a Protostellar Core
Shih-Ying Hsu, Chin-Fei Lee, Doug Johnstone +25
Interstellar complex organic molecules (COMs) in solar-like young stellar objects (YSOs), particularly within protostellar disks, are of significant interest due to their potential…
Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone

We present so far the highest resolution (0.04") ALMA 1.3 mm continuum observations of three massive star-forming clumps in the Central Molecular Zone, namely 20 km s…
ALMA observations of massive clouds in the central molecular zone: slim filaments tracing parsec-scale shocks
Kai Yang, Xing Lu, Yichen Zhang +22
The central molecular zone (CMZ) of our Galaxy exhibits widespread emission from SiO and various complex organic molecules (COMs), yet the exact origin of such emission is uncertai…
Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud
Xunchuan Liu, Tie Liu, Pak-Shing Li +17
The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…
