MIAO-ALMA: Shocks and Protostellar Outflows in 70 m-dark clumps with 1 /
Shuting Lin, Siyi Feng, Junzhi Wang +16
To investigate the initial conditions of high-mass star-forming regions, we use SiO (2-1) emission to trace early shock-related kinematics toward sixteen 70 m-dark and massive c…
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…
