Other Cups Projects Classical Mechanics Simulations Electricity and Magnetism Simulations Modern Physics Simulations Nuclear and Particle Physics Simulations Quantum Mechanics Simulations Solid State Physics Simulations Thermal and Statistical Physics Simulations Waves and Optics Simulations Astrophysics Simulations is one volume in a series of nine book/software packages developed by the Consortium for Upper-Level Physics Software. CUPS is an international group of 27 physicists, all with extensive backgrounds in the research, teaching, and development of instructional software. The simulations included in this volume cover: Stellar Evolution, The Interior Model of Star, Binary Stars, The Motion of n Bodies, Galactic Kinematics, Stellar Pulsation, and Stellar Atmospheres. These simulations include complex, often realistic, calculations of models of various physical systems. If desired, the user may also vary many parameters of the system, and interact with it in other ways, so as to study its behavior in real time. Source code has been provided for users who wish to modify programs. All of the programs are written in Borland/Turbo Pascal for MS-DOS. Minimum hardware requirement is an IBM-compatible 386-level machine with mouse and VGA color monitor. The disk(s) included in this package are 5.5???.
