Theoretical Astrophysics: An Introduction 1st Edition by Matthias Bartelmann (PDF)

Description

Beginning from first principles and adopting a modular structure, this book develops the fundamental physical methods needed to describe and understand a wide range of seemingly very diverse astrophysical phenomena and processes. For example, the discussion of radiation processes including their spectra is based on Larmor’s equation and extended by the photon picture and the internal dynamics of radiating quantum systems, leading to the shapes of spectral lines and the ideas of radiation transport. Hydrodynamics begins with the concept of phase-space distribution functions and Boltzmann’s equation and develops ideal, viscous and magneto-hydrodynamics all from the vanishing divergence of an energy-momentum tensor, opening a natural extension towards relativistic hydrodynamics. Linear stability analysis is introduced and used as a common and versatile tool throughout the book. Aimed at students at graduate level, lecturers teaching courses in theoretical astrophysics or advanced topics in modern astronomy, this book with its abundant examples and exercises also serves as a reference and an entry point for more advanced researchers wanting to update their knowledge of the physical processes that govern the behavior and evolution of astronomical objects.

⭐I first bought this book for a master course on theoretical astrophysics two years ago. Science then I frequently worked with this book to read up on specific topics. Bynow I work in the astrophysical research and this book is still one of my favorites.If carefully read from cover to cover, it provides a perfect basis for further studies. For an introductory book, it is on a very high level and offers manydetails. Results are not simply stated but the calculations leading up to this results are performed. Also, the author takes time to discuss the physical interpretations.Personally I especially like about this book, that it clearly indicates when simplifications and assumptions enter and why they are sensible. And in cases where suchsimplifications are not allowed, the full relativistic or quantum mechanical calculations are performed.Thus I would recommend this book to anyone looking for a broad introduction to astrophysical processes and is not afraid to spend some effort on the underlying calculations.

⭐Ich habe mir das Buch als Begleitmaterial zur gleichlautenden Vorlesung als E-Book gekauft. Dieses ist sogar teuer als die Papierversion! Das Layout ist recht unübersichtlich und am schlimmsten ist, dass die Formeln so klein sind. Sie sind auf den Kindles (ich habe PaperWhite und den alten) nur selten lesbar. Somit ist das E-Book unterwegs nicht nutzbar. Auf dem PC geht es halbwegs. Ich werde es wohl gegen die Papierversion eintauschen, da ich das Buch benötige, denn der Professor geht danach vor.Vor dem Kauf empfehle ich, sich eine Leseprobe anzuschauen und ein eigenes Urteil auch bzgl. der Sprache zu bilden.Noch ein Update: Auch auf dem Kindle HD Fire sind die Formeln kaum lesbar. Das Hauptproblem bei diesem E-Book ist, dass die Formeln nicht vergrößerbar sind. Die Schrift kann man zwar so weit vergrößern, dass man sie aus 4m Abstand lesen kann, aber die Formeln bleiben gleich groß. Sehr schade. Habe das Buch heute im Rahmen der 7-tägigen Kindle-Garantie zurückgegeben.
