Molecule-dependent Abundance Behavior of Oxygen-bearing Complex Organics in High-Mass Star-Forming Regions: A Uniform 50-source Survey
Xuefang Xu, Mingwei He, Qian Gou +10
We present a uniform IRAM-30\,m survey analysis of four oxygen-bearing complex organic molecules (COMs), methanol (CHOH), acetaldehyde (CHCHO), methyl formate (CHOCHO),…
The evolution of C4H and c-C3H2 in molecular cores
Yijia Liu, Junzhi Wang, Ningyu Tang +8
Linear C4H and cyclic c-C3H2, as small unsaturated hydrocarbons, are the key precursors to complex organic molecules and are critical components of the interstellar medium. We pres…
Tentative Detection of the Glycine Isomer Glycolamide in Hot Molecular Core
Chunguo Duan, Fengwei Xu, Qian Gou +6
Understanding whether prebiotic molecules can endure and reform through the energetic stages of star formation is essential for tracing the continuity of interstellar chemistry tow…
An ALMA Study of Molecular Complexity in the Hot Core G336.99-00.03 MM1
Chunguo Duan, Qian Gou, Tie Liu +9
High-mass star formation involves complex processes, with the hot core phase playing a crucial role in chemical enrichment and the formation of complex organic molecules. However,…
Observational studies on S-bearing molecules in massive star forming regions
R. Luo, J. Z. Wang, X. Zhang +9
Aims. We present observational results of HS 1-1, HS 1-1, HCS 5-4, HCS 4-3, SiO 4-3, HCN 19-18 and C$…
The deuterium fractionation of NH in massive star-forming regions
Yuqiang Li, Junzhi Wang, Juan Li +6
Deuteration is sensitive to environmental conditions in star-forming regions. To investigate NHD chemistry, we compared the spatial distribution of ortho-NHD $1_{11}^s-1_{0…
