<Subrahmanyan Chandrasekhar> investigated stellar structure and stability by connecting microscopic <physics> to the equilibrium of entire <stars>. His analysis of <white dwarfs> included the effect of <special relativity> on the <electron degeneracy pressure> supporting them against <gravity>.
At sufficiently high <mass density>, increasing <density> does not make that support grow rapidly enough to balance arbitrarily large stellar <mass>. The resulting <Chandrasekhar limit> is about 1.4 <solar mass>[solar masses] for the usual composition assumption. It is a limit for this form of stellar support, with major consequences for the possible endpoints of <stellar evolution>.<On Stars, Their Evolution and Their Stability by Subrahmanyan Chandrasekhar>[White-dwarf equilibrium, relativistic degeneracy and limiting-mass discussion]{ref}
