In astrophysics, dynamical friction or Chandrasekhar friction, sometimes called gravitational drag, is loss of momentum and kinetic energy of moving bodies through gravitational interactions with surrounding matter in space. It was first discussed in detail by Subrahmanyan Chandrasekhar in 1943. [1] [2] [3]
The Chandrasekhar limit (/ ˌ tʃ ə n d r ə ˈ ʃ eɪ k ər /) [1] is the maximum mass of a stable white dwarf star. The currently accepted value of the Chandrasekhar limit is about 1.4 M ☉ ( 2.765 × 10 30 kg ).
In atmospheric radiation, Chandrasekhar's X- and Y-function appears as the solutions of problems involving diffusive reflection and transmission, ...
Subrahmanyan Chandrasekhar (/ ˌ tʃ ə n d r ə ˈ ʃ eɪ k ər /; [3] 19 October 1910 – 21 August 1995) [4] was an Indian-American theoretical physicist who made significant contributions to the scientific knowledge about the structure of stars, stellar evolution and black holes.
Chandrasekhar also noted that Einstein's only guides in his search for an exact theory were the principle of equivalence and his sense that a proper description of gravity should be geometrical at its basis, so that there was an "element of revelation" in the manner in which Einstein arrived at his theory. [21]
In the Chandrasekhar–Eddington dispute of the early 20th century, English astronomer Arthur Eddington and Indian astronomer Subrahmanyan Chandrasekhar disagreed over the correct theory to describe the final stages of a star's lifecycle. During the dispute, Chandrasekhar was at the beginning of his career and Eddington was a renowned physicist ...

In physics and mathematics, the Klein–Kramers equation or sometimes referred as Kramers–Chandrasekhar equation [1] is a partial differential equation that describes the probability density function f (r, p, t) of a Brownian particle in phase space (r, p). [2] [3] It is a special case of the Fokker–Planck equation.
