AS101 Lecture Notes - Lecture 6: Stellar Kinematics, Sound, Star Cluster
Document Summary
Chapter 7: the structure and formaion of stars. One of the basic laws of stellar structure: the weight on each layer must be balanced by the pressure in that layer. The law of energy transport says that energy must low from hot regions to cooler regions either by: conducion, convecion, or, radiaion. The resistance of a gas to the passage of radiaion. Represents ability of stellar material to absorb radiaion, or 1/ (heat conducivity). All microscopic processes that can absorb photons at each frequency v. also related to the mean free path of the paricles. A table of numbers represening the condiions in various layers within a star. There are four known forces in nature: the force of gravity, the electromagneic force, the strong nuclear force (binds together atomic nuclei, weak nuclear force (involved in radioacive decay) Nuclear power plants generate energy via nuclear ission (spliing of nuclei)
