This book gives the reader some basic knowledge of these processes and at the same time, presents estimates of the main quantities relevant to the study of the interstellar medium. The book could be used as an introductory course on the interstellar medium  by science students or by readers interested in astrophysics with an adequate physics and mathematics background.AstronomyAstrophysicsSpace sciencesAstronomy, Astrophysics and Cosmologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P22006Astrophysics and Astroparticleshttps://scigraph.springernature.com/ontologies/product-market-codes/P22022Space Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics)https://scigraph.springernature.com/ontologies/product-market-codes/P22030Astronomy.Astrophysics.Space sciences.Astronomy, Astrophysics and Cosmology.Astrophysics and Astroparticles.Space Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics).523.1/135523.1135Maciel Walter Jauthttp://id.loc.gov/vocabulary/relators/aut791797MiAaPQMiAaPQMiAaPQBOOK9910437981703321Astrophysics of the Interstellar Medium1992252UNINA
