Interferometric molecular line observations toward the 21 μm protoplanetary nebula IRAS 06530-0213
Hao-Min Sun, Zhuang Zhang, Jun-Yang Liu +2
The paper presents high‑resolution interferometric observations of HC₃N, C₄H, and SiC₂ toward the 21 µm protoplanetary nebula IRAS 06530‑0213, revealing that carbon‑chain molecules…
The ALMA-QUARKS Survey: Discovery of Dusty Fibrils inside Massive Star-forming Clumps
Yan-Kun Zhang, Tie Liu, Wenyu Jiao +35
We report the discovery of more than 323 superfine dusty filamentary structures (fibrils) inside 121 massive star forming clumps that are located in widely different Galactic envir…
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…
Cocoon-to-Butterfly Transformation in Protoplanetary Nebula: Detection of a Spherical Halo and a Barrel-shaped Torus in IRAS 065300213
Hao-Min Sun, Yong Zhang, Sheng-Li Qin
Protoplanetary nebulae (PPNs) represent a critical evolutionary bridging stage between the asymptotic giant branch (AGB) and planetary nebula (PN) stages. Their dynamical structure…
The ALMA-ATOMS Survey: Exploring Protostellar Outflows in HCN
Ariful Hoque, Tapas Baug, Lokesh K. Dewangan +25
We present the first systematic study of bipolar outflows using HCN as a tracer in a sample of 146 massive star-forming regions from ALMA-ATOMS survey. Protostellar outflows ar…
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…
