Abstract
Stars form within molecular clouds but our understanding of this fundamental process remains hampered by the complexity of the physics that drives their evolution. We review our observational and theoretical knowledge of molecular clouds trying to confront the two approaches wherever possible. After a broad presentation of the cold interstellar medium and molecular clouds, we emphasize the dynamical processes with special focus to turbulence and its impact on cloud evolution. We then review our knowledge of the velocity, density and magnetic fields. We end by openings towards new chemistry models and the links between molecular cloud structure and star-formation rates.
期刊介绍：
The Astronomy and Astrophysics Review is a journal that covers all areas of astronomy and astrophysics. It includes subjects related to other fields such as laboratory or particle physics, cosmic ray physics, studies in the solar system, astrobiology, instrumentation, and computational and statistical methods with specific astronomical applications. The frequency of review articles depends on the level of activity in different areas. The journal focuses on publishing review articles that are scientifically rigorous and easily comprehensible. These articles serve as a valuable resource for scientists, students, researchers, and lecturers who want to explore new or unfamiliar fields. The journal is abstracted and indexed in various databases including the Astrophysics Data System (ADS), BFI List, CNKI, CNPIEC, Current Contents/Physical, Chemical and Earth Sciences, Dimensions, EBSCO Academic Search, EI Compendex, Japanese Science and Technology, and more.
