论文摘要
我们研究了相对论恒星内部夸克物质中夸克数密度的手性磁波（CMW）的新型星体遗迹，而相对论中微子数量密度密度的相对论恒星和核心偏转超新星和核心中微子数量密度的手性涡流波（CVW）在超级新核心的核心中核心物质中。我们称这些手性波的振荡模式分别为手性磁模式（CM模式）和手性涡度模式（CV模式）。由于有限的夸克质量和扩散，我们在手性翻转的情况下得出了这些新模式的分散关系。然后，我们估计这些模式的可能频率和所得重力波的幅度。特别是，由于CM模式只能在夸克物质中存在，几乎无间隙的夸克（例如两种味道颜色超导性）对于足够强的磁场，相应的引力波为中子恒星中的夸克物质和磁场提供了新的可能的探测。
We study the novel asteroseismology of the chiral magnetic wave (CMW) of the quark number density in relativistic quark matter inside neutron stars and core-collapse supernovae and the chiral vortical wave (CVW) of the neutrino number density in relativistic neutrino matter at the core of supernovae. We call the oscillation modes for these chiral waves the chiral magnetic mode (CM-mode) and chiral vortical mode (CV-mode), respectively. We derive the dispersion relations of these new modes in the presence of the chirality flipping due to the finite quark mass and diffusion. We then estimate the possible frequencies of these modes and amplitudes of the resulting gravitational waves. In particular, since the CM-mode can exist only in quark matter with nearly gapless quarks (such as the two-flavor color superconductivity) for a sufficiently strong magnetic field, corresponding gravitational waves provide a new possible probe for such quark matter and the magnetic field in neutron stars.
