超子星中的强子-夸克混合相

Hadron-quark mixed phase in hyperon stars

Toshiki Maruyama, Satoshi Chiba, Hans-Josef Schulze, Toshitaka Tatsumi

摘要:

分析了中子星中β稳定物质(包括超子)中强子-夸克相变的不同可能性。我们使用的Brueckner-Hartree-Fock方法包括超子的强子状态方程和广义MIT袋模型的夸克部分。然后,我们详细指出麦克斯韦和吉布斯相变结构之间的差异,包括表面张力和电磁屏蔽的影响。我们发现只有一个小的影响,最大中子星质量,而半径的恒星,特别是其内部结构的影响更大。

英文摘要:

We analyze the different possibilities for the hadron-quark phase transition occurring in beta-stable matter including hyperons in neutron stars. We use a Brueckner-Hartree-Fock approach including hyperons for the hadronic equation of state and a generalized MIT bag model for the quark part. We then point out in detail the differences between Maxwell and Gibbs phase transition constructions including the effects of surface tension and electromagnetic screening. We find only a small influence on the maximum neutron star mass, whereas the radius of the star and in particular its internal structure are more affected.
