手征SU(3)模型中的原中子和中子星

Proto-Neutron and Neutron Stars in a Chiral SU(3) Model

V. Dexheimer, S. Schramm

摘要:

考虑到中微子的俘获、有限的温度和熵,我们将强子手征SU(3)模型应用于中子星和原中子星。过渡到手征恢复阶段的研究和全球性质的恒星一样,最小和最大的质量和半径计算不同的情况下。此外,还考虑了自转对中子星质量的影响,重子数和角动量守恒决定了冷却过程中自转的最大频率。

英文摘要:

A hadronic chiral SU(3) model is applied to neutron and proto-neutron stars, taking into account trapped neutrinos, finite temperature and entropy. The transition to the chirally restored phase is studied and global properties of the stars like minimum and maximum masses and radii are calculated for different cases. In addition, the effects of rotation on neutron star masses are included and the conservation of baryon number and angular momentum determine the maximum frequencies of rotation during the cooling.
