强子和夸克-强子模型中的核物质、原子核和中子星

Nuclear matter, nuclei, and neutron stars in hadron and quark-hadron models

S. Schramm, V. Dexheimer, R. Negreiros, T. Schürhoff

摘要:

我们发展了一个强子和夸克的统一模型。在这种方法中,我们调查的模型作为温度和化学势的函数的相结构。计算冷物质的状态方程,我们确定中子和混合星的质量和半径。在调查的延伸,我们考虑了紧凑型恒星的冷却行为,并推导出恒星的质量和旋转和它的冷却行为之间的一般关系。最后,我们研究的影响,德尔塔共振的恒星物质,特别是相对于可能的解决方案,小半径的恒星。

英文摘要:

We develop a unified model of hadrons and quarks. Within this approach we investigate the phase structure of the model as function of temperature and chemical potential. Computing the equation of state of cold matter we determine neutron and hybrid star masses and radii. In an extension of the investigation we consider the cooling behavior of the compact stars and derive a general relation between the star's mass and rotation and its cooling behavior. Finally we study the effect of Delta resonances for star matter, especially with respect to possible solutions of stars with small radii.
