The Virial Theorem in Stellar Astrophysics
by George W. Collins, II
Publisher: Pachart Pub. House 1978
Number of pages: 135
The virial theorem is extremely powerful in understanding problems of stellar astrophysics, but it is also poorly understood by many who study the subject. The author has not prepared here a complete and exhaustive discussion of the virial theorem; rather this effort should be viewed as a guided introduction, punctuated by a few examples.

Cold and dense nuclear and quark matter can be found in the interior of compact stars. The author gives a pedagogical introduction to microscopic calculations based on phenomenological models, effective theories, and perturbative QCD.

A supernova is a stellar explosion that briefly outshines an entire galaxy, radiating as much energy as the Sun or any ordinary star is expected to emit over its entire life span, before fading from view over several weeks or months.
