An Eccentric Massive Protobinary Assembled via a Core-merger Parabolic Encounter
Yao Wang, Yichen Zhang, Rubén Fedriani +14
Most massive stars form in binary systems, which profoundly influence their subsequent evolution. However, how such systems form remains poorly understood, with several competing s…

Kolmogorov turbulence across multi-fractal gas in Polaris Flare
Xunchuan Liu, Pak-Shing Li, Yihuan Di
We reveal a pristine, scale-invariant 3D Kolmogorov velocity cascade () spanning --~pc in the Polaris Flare using \texttt{PPCOS} $^{12}\text{C…

Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud
Xunchuan Liu, Tie Liu, Pak-Shing Li +17
The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…
