夸克物质对致密星观测性质的影响

Quark matter influence on observational properties of compact stars

Sjoerd Hardeman

摘要:

致密恒星的密度可能使夸克不再被限制在强子中,而是表现为弱相互作用粒子。在这种情况下,微扰计算是可能的。然而,由于高压和强作用力中的吸引通道,夸克在超流状态下的凝聚是可能的。这可能对磁场产生有趣的影响,特别是与致密恒星中慢周期自由进动的发现有关。在这篇论文中,将讨论由夸克物质构成的致密星的质量-半径关系以及具有夸克物质核心的致密星中的磁场行为。

英文摘要:

Densities in compact stars may be such that quarks are no longer confined in hadrons, but instead behave as weakly interacting particles. In this regime perturbative calculations are possible. Yet, due to high pressures and an attractive channel in the strong force, condensation of quarks in a superfluid state is likely. This can have interesting consequences for magnetic fields, especially in relation to the discovery of slow-period free precession in a compact star. In this proceedings there will be a discussion of the mass-radius relations of compact stars made from quark matter and magnetic field behaviour in compact stars with a quark matter core.
