This book covers all aspects of opacity and equations of state for gases, plasmas, and dust. The discussion emphasizes the continuous transformation of the equilibrium compositions of these phases as a function of temperature and density.

Dr. Walter F. Huebner is a research scientist with the Southwest Research Institute in San Antonio, Texas.
