Chandrasekhar was active in stellar dynamics only during the five years 1939 – 1944. Over this period the focus of his attention varied systematically, so that a chronological ordering of his papers corresponds fairly exactly with an ordering by topic. In sections 2 and 3 I review in chronological order all the stellar-dynamical papers that he published in refereed journals. Section 4 summarizes the content of his book The Principles of Stellar Dynamics. Section 5 attempts to assess the impact… 

Heterogeneous parallel algorithm design and performance optimization for WENO on the Sunway Taihulight supercomputer

TLDR
A heterogeneous parallel algorithm design and performance optimization of a high-order WENO on Sunway TaihuLight is presented, which can achieve up to 172X speedup on one single node, and additional 58X speed up on 64 nodes, with nearly linear scalability.

Dynamical evolution of globular clusters

One of the world's most distinguished astrophysicists presents a comprehensive theoretical treatment of the dynamical evolution of globular clusters. Lyman Spitzer's research in this field

Dynamical fate of wide binaries in the solar neighborhood

An analytical model is presented for the evolution of wide binaries in the Galaxy. The study is pertinent to the postulated solar companion, Nemesis, which may disturb the Oort cloud and cause

The diffusion of stars through phase space

Deviations of the potentials of stellar systems from integrability cause stars to diffuse through three-dimensional orbit space. The Fokker–Planck equation that describes this diffusion takes a

Dynamical friction. II. The rate of escape of stars from clusters and the evidence for the operation of dynamical friction

In this paper a general method is described for determining the rate of escape of stars from galactic and globular clusters which is based on certain general statistical principles. Essentially the

Dynamical Friction. III. A more exact theory of the rate of escape of stars from clusters

A more exact estimate of the rate of escape of stars from clusters is made than in an earlier paper by properly allowing for the dependence of the coefficient of dynamical friction on the velocity.

The statistics of the gravitational field arising from a random distribution of stars. IV. The stochastic variation of the force acting on a star

In this paper the theory of the stochastic variation of the force acting on a star is considered, and the solution to the formal problem is obtained in terms of the average force per unit mass F t

The Statistics of the Gravitational Field Arising from a Random Distribution of Stars. I. The Speed of Fluctuations.

This paper is devoted principally to a statistical analysis of the speed of the fluctuations in the gravitational field acting at some fixed point in a system containing a random distribution of mass

Dynamical friction. I. General considerations: the coefficient of dynamical friction

In this paper it is shown that a star must experience dynamical friction, i.e., it must suffer from a systematic tendency to be decelerated in the direction of its motion. 'This dynamical friction

The Statistics of the Gravitational Field Arising from a Random Distribution of Stars. III. The Correlations in the Forces Acting at Two Points Separated by a Finite Distance.

In this paper we consider the theory of the correlations in the forces acting at two points separated by a finite distance in a system containing a random distribution of stars. A problem central in

WEAKLY DAMPED MODES IN STAR-CLUSTERS AND GALAXIES

A perturber may excite a coherent mode in a star cluster or galaxy. If the stellar system is stable, it is commonly assumed that such a mode will be strongly damped and therefore of little practical
