Water maser detections toward 70 m infrared dark clumps at early star formation stage
Chao Ou, Shanghuo Li, Junzhi Wang +2
Water masers provided powerful probes of shocked gas and protostellar activity during the early stages of star formation. Using VLA K-band observations of the 22 GHz water line, we…
The gas kinematics in 70 μm dark molecular clumps with ammonia
Chao Ou, Shanghuo Li, Junzhi Wang +5
We present the investigation of the gas kinematics and assess the evolutionary stages of dense cores embedded in four infrared dark clouds (IRDCs) using the NH(1,1) and NH(…
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…
CH3CCH as a thermometer in warm molecular gas
Yuqiang Li, Junzhi Wang, Juan Li +9
Kinetic temperature is a fundamental parameter in molecular clouds. Symmetric top molecules, such as NH and CHCCH, are often used as thermometers. However, at high temperat…
DCO and DCN 1-0 survey toward a sample of Planck cold clumps
Fu Mo, Junzhi Wang, Shu Liu +8
Deuterated molecules can be used to study the physical conditions and the astro-chemical evolution of molecular clouds. large-sample surveys for deuterated molecules are needed to…
NN abundance ratio toward massive star-forming regions with different Galactic distances
Chang Ruan, Junzhi Wang, Chao Ou +2
The abundance ratio of NN is, in principle, a powerful tool for tracing stellar nucleosynthesis. This work aims to measure and analyze (N/N)($^…
Dense Outflowing Molecular Gas in Massive Star-forming Regions
Yani Xu, Junzhi Wang, Shu Liu +6
Dense outflowing gas, traced by transitions of molecules with large dipole moment, is important for understanding mass loss and feedback of massive star formation. HCN 3-2 and HCO$…
OO abundance ratio toward a sample of massive star forming regions with parallax distances
Chao Ou, Junzhi Wang, Siqi Zheng +3
The OO abundance ratio is, in principle, a powerful tool to estimate the relative contributions of massive stars and low- to intermediate-mass stars to the chemical…
