The ALMA-QUARKS Survey: Properties of Hot Molecular Fragments in the Massive Protocluster IRAS 17233-3606
Li Chen, Sheng-Li Qin, Dongting Yang +29
To investigate the physical mechanisms of fragmentation within the hot molecular core of the massive protocluster IRAS 17233-3606 (G351.78-0.54), we carried out a detailed analysis…
The ALMA-QUARKS survey: Investigating Thermal Feedback of Massive Protostars in Hot Molecular Cores
Dezhao Meng, Tie Liu, Jarken Esimbek +33
We identify a sample of 83 spatially resolved hot molecular cores (HMCs) in the QUARKS survey, aiming at investigating thermal feedback from massive stars. Using CHCN\,(12--11)…
The ALMA-ATOMS survey: Methanol emission in a large sample of hot molecular cores
Jiahang Zou, Tie Liu, Sheng-Li Qin +26
Methanol (CHOH) is a key complex organic molecule (COM) in the interstellar medium, widely used as a tracer of dense gas and hot molecular cores (HMCs). Using high-resolution…
The ALMA-ATOMS-QUARKS survey: Resolving a chemically rich massive protostellar outflow
Jia-Hang Zou, Tie Liu, Fengwei Xu +19
We present a comprehensive study on the physical and chemical structures of a chemically rich bipolar outflow in a high-mass star forming region IRAS 162724837 (SDC335), utilizi…
The ALMA-QUARKS survey: Hot Molecular Cores are a long-standing phenomenon in the evolution of massive protostars
Dezhao Meng, Tie Liu, Jarken Esimbek +34
We present an analysis of the QUARKS survey sample, focusing on protoclusters where Hot Molecular Cores (HMCs, traced by CH3CN(12--11)) and UC HII regions (traced by H30α/H40α) c…
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…
