Collisionless Stellar Dynamics

Astrophysics and Space Science, 1971
Collisionless Stellar Dynamics deals with Stellar Systems for times small with respect to the relaxation time. Thus it disregards completely individual encounters between stars. Our basic equation is the collisionless Boltzmann equation $$ \frac{{\partial f}}{{\partial t}} + \bar v \cdot \frac{{\partial f}}{{\partial \bar x}} - \frac{{\partial V}}{{

Statistical Hypotheses in Stellar Dynamics

Physical Review, 1946
This paper starts with a short review of the usual methods of stellar dynamics and analyzes the underlying hypotheses. The most successful approach to stellar dynamics has been the one which neglects interactions between nearby stars (because they are weak) and takes into consideration the motion of stars in a smooth field of force only, produced by ...

Stellar Dynamics and Molecular Dynamics: Possible Analogies

2003
In stellar dynamics one is accostumed to deal with the Lynden-Bell distribution, which presents two peculiar characteristics: a) it resembles the quantum Fermi-Dirac distribution, and b) describes a state of metaequilibrium, that is expected to evolve on much longer time scales to a standard Maxwell-Boltzmann equilibrium.

Introduction to Stellar Dynamics

2021
The study of stellar dynamics is experiencing an exciting new wave of interest thanks to observational campaigns and the ready availability of powerful computers. Whilst its relevance includes many areas of astrophysics, from the structure of the Milky Way to dark matter halos, few texts are suited to advanced students.

Principles of Stellar Dynamics

Physics Bulletin, 1961
By S. Chandrasekhar New York: Dover Publications, Inc. Pp. x+313. Price $2.00 Among the classics of physics and astronomy now reappearing in the Dover edition, it is especially pleasing to welcome this book, which nearly twenty years ago developed the application of generalized dynamics to the largest assemblage of " molecules " known, the hundred ...

Regularization in stellar dynamics

Bulletin astronomique, 1968
On présente les traitements numériques et analytiques des rencontres (ainsi que des collisions doubles) en utilisant le modèle du problème gravitationel des n corps. L'effet du champ Newtonien de gravitation devient infini quand la distance des corps mis en jeu tend vers zéro.

Stellar Evolution, Stellar Dynamics and Tera-Flops Computation

2001
In 1995 GRAPE project completed a special-purpose computer of Tera­flops speed which was dedicated to gravitational many-body problem in astrophysics. Here described is a sequence of scientific motivations which led me to the project. The success of the GRAPE machine seems to have shown that dedicated computers are necessary components in construct­ing
