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…
Probing Star-Forming Properties via ALMA Observations of Massive Protocluster IRAS 15596-5301
Faxian Chang, Mengyao Tang, Tie Liu +8
To deepen our understanding of star-forming properties, we studied a massive protocluster IRAS 15596-5301 using ALMA 870 um and 3 mm data. High-resolution 870 um data reveal 34 den…
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…
The ALMA-ATOMS survey: A sample of weak hot core candidates identified through line stacking
Zi-Yang Li, Xunchuan Liu, Tie Liu +33
Hot cores represent critical astrophysical environments for high-mass star formation, distinguished by their rich spectra of organic molecular emission lines. We aim to utilize hig…
ALMA observations of CH3COCH3 and the related species CH3CHO, CH3OH, and C2H5CN in line-rich molecular cores
Chuanshou Li, Sheng-Li Qin, Tie Liu +10
Context. Acetone (CH3COCH3) is a carbonyl-bearing complex organic molecule, yet interstellar observations of acetone remain limited. Studying the formation and distribution of CH3C…
The ALMA-ATOMS survey: Vibrationally excited HCN lines in hot cores
Li Chen, Sheng-Li Qin, Tie Liu +26
Interstellar molecules are excellent tools for studying the physical and chemical environments of massive star-forming regions. In particular, vibrationally excited HCN (HC…
