在Dyson-Schwinger夸克模型中,在彩虹近似和Ball-Chiu顶点近似下,计算了奇异夸克物质的物态方程和奇异夸克星的内部结构。我们强调由于普通核物质的稳定性条件的模型的参数空间上的约束。考虑到这些限制,我们发现奇异夸克星的最大质量约为1.9个太阳质量,典型半径为9- 11公里。从中子星到奇异夸克星的转换中,我们得到了一个与沙格一样大的能量释放。
We calculate the equation of state of strange quark matter and the interior structure of strange quark stars in a Dyson-Schwinger quark model within rainbow or Ball-Chiu vertex approximation. We emphasize constraints on the parameter space of the model due to stability conditions of ordinary nuclear matter. Respecting these constraints, we find that the maximum mass of strange quark stars is about 1.9 solar masses, and typical radii are 9-11km. We obtain an energy release as large aserg from conversion of neutron stars into strange quark stars.
