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),…
Unveiling Central ortho-H2D+ Depletion at Sub-kau Scales in Prestellar Core G205.46-14.56M3: The First Interferometric Evidence and Implications for Deuterium Chemistry
Sheng-Jun Lin, Sheng-Yuan Liu, Dipen Sahu +8
Prestellar cores represent the initial conditions of star formation, but heavy molecules such as CO are strongly depleted in their cold, dense interiors, limiting the ability to pr…
The ALMA-QUARKS survey: Extensive detection of acetamide in multiple high-mass star-forming regions
Chunguo Duan, Xuefang Xu, Qian Gou +8
Acetamide (CHCONH), a key interstellar amide and a methyl derivative of formamide (NHCHO), has been sparsely detected, limiting insights into its prebiotic releva…
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,…
