夸克物质对磁化中子星heat capacity的贡献
Quark matter contribution to the heat capacity of magnetized neutron stars
摘要：
在本文中，我们找到了致密夸克物质的磁双手征密度波（MDCDW）相的热容，并利用它来探讨中子星内部磁双手征密度波相的可行性。MDCDW是夸克物质的空间不均匀相，已知在中等密度下比手征对称相和色味锁定超导相更受青睐。通过将我们的结果与瞬时吸积中子星的观测结果建立的核心热容的下限进行比较，我们表明MDCDW夸克物质的热容远高于该下限，因此不能被排除。这一结果增加了丰富的补充调查，所有这些都有助于加强由MDCDW夸克物质组成的中子星内部的可行性。为了完整性，我们审查的贡献的主要中子星成分在低，高和中等密度，有和没有存在的磁场的热容量。
英文摘要：
In this paper, we find the heat capacity of the magnetic dual chiral density wave (MDCDW) phase of dense quark matter and use it to explore the feasibility of this phase for a neutron star interior. MDCDW is a spatially inhomogeneous phase of quark matter known to be favored at intermediate densities over the chirally symmetric phase and the color-flavor-locked superconducting phase. By comparing our result to the lower limit of the core heat capacity established from observations of transiently accreting neutron stars, we show that the heat capacity of MDCDW quark matter is well above that lower limit and hence cannot be ruled out. This result adds to a wealth of complementary investigations, all of which has served to strengthen the viability of a neutron star interior made of MDCDW quark matter. For completeness, we review the contributions to the heat capacity of the main neutron star ingredients at low, high and intermediate densities, with and without the presence of a magnetic field.
