Filamentary structures identified in far-infrared observations of molecular clouds are typically
found to have full widths at half-maximum. However, the physical explanation for this …

A generalized nonideal magnetohydrodynamic (MHD) model to explore the excitation
dynamics of the gravitational (Jeans) instability in a spherical complex molecular cloud is …

Based on general polytropic (GP) magnetohydrodynamics (MHD), we offer a self-similar
dynamic formalism for a magnetized, infinitely long, axially uniform cylinder of axisymmetry …

Observations strongly suggest that filaments in galactic molecular clouds are in a non-
thermal state. As a simple model of a filament, we study a two-dimensional system of self …

In this study, we consider the effects of ambipolar diffusion during the gravitational collapse
of a radiative cooling filamentary molecular cloud. Two separate configurations of magnetic …

We present a theoretical model framework for general polytropic (GP) hydrodynamic
cylinder under self-gravity of infinite length with axial uniformity and axisymmetry. For self …

We explore self-similar hydrodynamics of general polytropic (GP) and isothermal cylinders
of infinite length with axial uniformity and axisymmetry under self-gravity. Specific entropy …

Recently, the self-similar collapse of the polytropic cylinders in the ideal MHD regime has
been targeted by many theoretical works. However, it has not yet been fully understood in …

In broad astrophysical contexts of large-scale gravitational collapses and outflows and as a
basis for various further astrophysical applications, we formulate and investigate a …

This work aims to investigate the dynamic behavior of ambipolar diffusion during the
gravitational collapse of a filamentary molecular cloud undergoing radiative cooling. The …
