A 3 mm line survey towards the circumstellar envelope of the carbon-rich AGB star IRC+10216 (CW Leo)
Juan Tuo, Xiaohu Li, Jixian Sun +14
We present an unbiased 3 mm spectral line survey (between 84.5 and 115.8 GHz), conducted by the Purple Mountain Observatory 13.7 meter radio telescope, together with updated mo…
Gas-phase molecules in protoplanetary nebulae with the 21 μm emission feature
Jian-Jie Qiu, Yong Zhang, Jun-ichi Nakashima +6
It has been more than 30 years since the enigmatic 21 μm emission feature was first discovered in protoplanetary nebulae (PPNs). Although dozens of different dust carrier candidate…
Systematic Search for Water Fountain Candidates using the Databases of Circumstellar Maser Sources
Haichen Fan, Jun-ichi Nakashima, D. Engels +6
Water fountains (WFs) are thought to be objects in the morphological evolution of the circumstellar envelopes of low- and intermediate-mass evolved stars, transitioning from spheri…
A 3 mm Molecular Line Survey toward The C-star Envelope CIT 6
Kui-Lu Yang, Yong Zhang, Jian-Jie Qiu +2
We present an unbiased molecular line survey toward the carbon-rich circumstellar envelope CIT 6 carried out between 90 and 116 GHz with the Arizona Radio Observatory 12 m telescop…
Interstellar Nitrogen Isotope Ratios: New NH3 Data from the Galactic Center out to the Perseus Arm
J. L. Chen, J. S. Zhang, C. Henkel +10
Our aim is to measure the interstellar 14N/15N ratio across the Galaxy, to establish a standard data set on interstellar ammonia isotope ratios, and to provide new constraints on t…
