Random gas motions inside sub-parsec scale supercritical filaments
Chao Zhang, Tie Liu, Mika Juvela +12
Supercritical gas filaments in molecular clouds host the dense cores in which new stars form. The mechanisms governing their formation and subsequent gas accretion remain poorly un…

Regular black hole with sub-Planckian curvature and suppressed exponential mass inflation
Zhong-Wen Feng, Hong-Lin Liu, Yi Ling +1
We construct a static spherically symmetric regular black hole with a Minkowski core, and a degenerate inner horizon with vanishing surface gravity. The spacetime contains a non-ex…

The evolution of molecular clouds: turbulence-regulated global radial collapse
An-Xu Luo, Hong-Li Liu, Jin-Zeng Li
The star formation efficiency (SFE) measures the proportion of molecular gas converted into stars, while the star formation rate (SFR) indicates the rate at which gas is transforme…
