双味混合星的Dyson-Schwinger夸克模型

Two-flavor hybrid stars with the Dyson-Schwinger quark model

J. -B. Wei, H. Chen, H. -J Schulze

摘要:

我们研究了Dyson-Schwinger模型中双味夸克物质的性质,并研究了混合中子星的可能后果,特别是关于两个太阳质量的限制。我们发现,在模型参数的某些极端值下,重中子星中双味夸克物质的质量分数可以高达30%,核子中子星到混合星转换过程中可能释放的能量可以达到$10^{52}\;$ erg.

英文摘要:

We study the properties of two-flavor quark matter in the Dyson-Schwinger model and investigate the possible consequences for hybrid neutron stars, with particular regard to the two-solar-mass limit. We find that with some extreme values of the model parameters, the mass fraction of two-flavor quark matter in heavy neutron stars can be as high as 30 percent and the possible energy release during the conversion from nucleonic neutron stars to hybrid stars can reach $10^{52}\;$erg.
