A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…

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)($^…

The orbital period of the long-period and colliding-wind binary WR 146 from radio interferometry of the shock cone
Shiming Wen, Bo Zhang, Shuangjing Xu +8
We report the first measurement of the orbital period of a long-period colliding-wind binary (CWB) system WR 146, derived by tracing the rotational morphology of its wind-colliding…
