Formation and Properties of Molecular Cloud Cores

TL;DR

This paper reviews the properties of dense molecular cloud cores, focusing on their formation, mass spectrum, lifetimes, and virial balance, based on 3D simulations of turbulent, magnetized, self-gravitating clouds.

Contribution

It provides a comprehensive analysis of core properties using advanced numerical simulations, highlighting the role of gravo-turbulent fragmentation in core formation.

Findings

Core mass spectrum aligns with observed distributions.

Lifetimes of cores are consistent with turbulent fragmentation timescales.

Virial analysis indicates cores are near equilibrium states.

Abstract

In this paper, we review some of the properties of dense molecular cloud cores. The results presented here rely on three-dimensional numerical simulations of isothermal, magnetized, turbulent, and self-gravitating molecular clouds (MCs) in which dense core form as a consequence of the gravo-turbulent fragmentation of the clouds. In particular we discuss issues related to the mass spectrum of the cores, their lifetimes and their virial balance.
