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…

Evolution of starless cores in massive clumps seen by the ALMA ASHES and QUARKS surveys

Dongting Yang, Hong-li Liu, Sheng-li Qin +28

We present a systematic comparative analysis of 324 starless cores in early-phase infrared-dark clouds (IRDCs; ASHES survey) and evolved-phase infrared-bright clouds (IRBCs; QUARKS…

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 Keplerian disk, envelope, and streamers surrounding an early O-type protostar in the Sagittarius C cloud of the Central Molecular Zone

Jixiang Weng, Xing Lu, Yu Cheng +22

Disk-mediated accretion is central to theories of massive star formation, setting the initial conditions for their evolution. Yet observations of Keplerian disks around early O-typ…

Q/W-band Observations toward Starless Cores in Orion (QWOSCO) I. Overview, Isotopologues, Isomers, and Complex Organics

Shih-Ying Hsu, Xunchuan Liu, Sheng-Yuan Liu +12

Molecular inventories in starless cores are powerful tools for probing the physical and chemical structures at the earliest stages of star formation. Wide-band spectral scans are i…

Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions

Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner +14

Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process on…
