The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

. The Virial Theorem of Clausius, which relates the average kinetic and potential energies of a dynamical system, is a powerful tool in astrophysics with a wide range of applications. I will show how the scalar form of the virial equilibrium equation is derived from first principles and demonstrate its utility in explaining the heating of contracting bodies, weighing supermassive black holes, and measuring the distances to far-flung galaxies.

Next: The Evolutionary Status of Up: No Title Previous: Massive X-ray Binaries . After 25 years of pulsar studies, a radiopulsar has been discovered in a binary system with a massive optical companion (Johnston et al. ... As shown in the very first calculations of joint evolution of NS and normal stars in binaries (Kornilov and Lipunov, 1983b[ 86 ]) a considerable fraction (maybe, the majority) of NS in binary systems having an optical companion must be at the ejector љ (E) state. ...
