From Diffuse Gas to Dense Molecular Cloud Cores [PDF]
, 2020 Molecular clouds are a fundamental ingredient of galaxies: they are the channels that transform the diffuse gas into stars. The detailed process of how they do it is not completely understood. We review the current knowledge of molecular clouds and their

Anatomy of Orion Molecular Clouds—The Astrochemistry Perspective/Approach
Frontiers in Astronomy and Space Sciences, 2021 The Orion molecular cloud (OMC) complex is the nearest and perhaps the best-studied giant molecular cloud complex within which low-mass and massive star formation occur. A variety of molecular species, from diatomic molecules to complex organic molecules

A Velocity Structure Analysis of Giant Molecular Cloud Associated with HII Region S152 [PDF]
Journal of Astronomy and Space Sciences, 2005 S152 is a small bright emission nebula located in the Perseus arm. Its optical diameter corresponds to 1.5 pc for an adopted distance 3.5 kpc. However, S152 is a part of a giant molecular cloud complex, which consists of several dense cores, containing ...

The Role of Magnetic Field in Molecular Cloud Formation and Evolution [PDF]
Frontiers in Astronomy and Space Sciences, 2019 We review the role that magnetic field may have on the formation and evolution of molecular clouds. After a brief presentation and main assumptions leading to ideal MHD equations, their most important correction, namely the ion-neutral drift is described.

The formation of molecular clouds [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 In a recent paper, Elmegreen (2000) has made a cogent case, from an observational point of view, that the lifetimes of molecular clouds are comparable to their dynamical timescales. If so, this has important implications for the mechanisms by which molecular clouds form.
