Exact and Quasi-exact Models of Strange Stars
arXiv:1006.4629 · doi:10.1142/S0218271810018128
Abstract
We construct and compare a variety of simple models for strange stars, namely, hypothetical self-bound objects made of a cold stable version of the quark-gluon plasma. Exact, quasi-exact and numerical models are examined to find the most economical description for these objects. A simple and successful parametrization of them is given in terms of the central density, and many differences among the models are explicitly shown and discussed.
