Thermodynamics of Strange Quark Matter with Density-dependent Bag Constant and Strange Stars
摘要
Abstract
Thermodynamics of strange quark matter are given by making use of MIT bag model with density-dependent bag parameter. Our results indicate that an extra term should be appended to the pressure expression of strange quark matter but not to the energy density when the bag constant is density-dependent, which assures self-consistency of the system. With this extra term, strange quark matter equations of state soften. At the same time, gravitational mass and corresponding radius of strange star decrease compared with the inconsistent case.关键词
