NO molecule in massive star forming regions

Shaomin Su, Junzhi Wang, Rui Luo +7

Context. Among diatomic molecules composed of the abundant elements C, N and O, NO has been detected far less than the well studied CN and CO, making it a crucial yet under-observe…

$^{14}$ N $/^{15}$ N abundance ratio toward massive star-forming regions with different Galactic distances

Chang Ruan, Junzhi Wang, Chao Ou +2

The abundance ratio of $^{14}$ N $/^{15}$ N is, in principle, a powerful tool for tracing stellar nucleosynthesis. This work aims to measure and analyze ( $^{14}$ N/ $^{15}$ N) $\times$ ($^…
