Part a century in the past, S. Chandrasekhar wrote those phrases within the preface to his 1 celebrated and winning e-book: during this monograph an test has been made to provide the idea of stellar dy namics as a department of classical dynamics - a self-discipline within the comparable common classification as celestial mechanics. [ ... ] certainly, a number of of the issues of recent stellar dy namical conception are so significantly classical that it truly is tricky to think that they're now not already mentioned, for instance, in Jacobi's Vorlesungen. seeing that then, stellar dynamics has constructed in numerous instructions and at var ious degrees, essentially 3 viewpoints closing from which to examine the issues encountered within the interpretation of the phenomenology. approximately talking, we will say stellar process (cluster, galaxy, etc.) will be con sidered from the perspective of celestial mechanics (the N-body challenge with N» 1), fluid mechanics (the process is represented by way of a cloth con tinuum), or statistical mechanics (one defines a distribution functionality for the positions and the states of movement of the parts of the system).
