CARPP: Parametric Radiative-Transfer Fitting of Molecular Cores from Dust Continuum Data
Yuchen Xing, Di Li, Nannan Yue +5
The density profiles of dense molecular cores are important indicators of their physical and evolutionary states. Multi-wavelength dust continuum data offers excellent constraints…
ALMA observations of Magnetic Fields in the Massive Star-forming Region IRAS 18360-0537
Shixian Mo, Keping Qiu, Qizhou Zhang +6
Assessing the significance of magnetic fields in high-mass star formation remains one of the most challenging topics in astrophysics. In this study, we present full polarization ob…
The gas kinematics in 70 μm dark molecular clumps with ammonia
Chao Ou, Shanghuo Li, Junzhi Wang +5
We present the investigation of the gas kinematics and assess the evolutionary stages of dense cores embedded in four infrared dark clouds (IRDCs) using the NH(1,1) and NH(…
The dominance of turbulence over magnetism in the formation of massive star cluster seeds
Junhao Liu, Patricio Sanhueza, Piyali Saha +32
High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…
Global and Local Infall in the ASHES Sample (GLASHES). II. Asymmetric Line Profiles around Dense Cores in 70 m Dark Massive Clumps
Kaho Morii, Patricio Sanhueza, Qizhou Zhang +1
Gravitational collapse is fundamental to star formation, yet direct kinematic evidence of infall at the core scale in high-mass star-forming regions remains poorly constrained. We…
Unveiling Dominant Toroidal Magnetic Fields in a Protostellar Outflow
Tao-Chung Ching, Zhi-Yun Li, Qizhou Zhang +6
Magnetic fields play a fundamental role in the formation of protostellar winds. In the magneto-centrifugal models, poloidal magnetic fields launch winds from accretion disks, and f…
