Interstellar Nitrogen Isotope Ratios: Measurements on tracers of CN and CN
J. L. Chen, J. S. Zhang, C. Henkel +6
The nitrogen isotope ratio 14N/15N is a powerful tool to trace Galactic stellar nucleosynthesis and constraining Galactic chemical evolution. Previous observations have found lower…

A Possible Chemical Clock in High-mass Star-forming Regions: N(HC3N)/N(N2H+)?
Y. X. Wang, J. S. Zhang, H. Z. Yu +5
We conducted observations of multiple HC3N (J = 10-9, 12-11, and 16-15) lines and the N2H+ (J = 1-0) line toward a large sample of 61 ultracompact (UC) H II regions, through the In…

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…
