论文摘要
在预计将发生在中子恒星地壳中的所谓意大利面积中，质子能够在空间中延伸，因此能够在大距离上轻松移动。因此，电流可以由质子携带，在传统的结晶物质中，具有分离的核。在强调具有类似片状核的所谓宽面条相的重点，我们描述了面食相的磁性，从而允许质子超导性。我们预测这些阶段将是II型超导体，并且我们计算通量线的每单位长度的能量，这被证明是强烈的各向异性。如果似乎很可能面食结构不完善，则将固定通量线，并且物质将以良好的电导体和通量衰减时间为长度。我们描述了我们结果的一些可能的天体物理表现。
In the so-called pasta phases predicted to occur in neutron star crusts, protons are able to move easily over large distances because the nuclear matter regions are extended in space. Consequently, electrical currents can be carried by protons, an effect not possible in conventional crystalline matter with isolated nuclei. With emphasis on the so-called lasagna phase, which has sheet-like nuclei, we describe the magnetic properties of the pasta phases allowing for proton superconductivity. We predict that these phases will be Type II superconductors and we calculate the energy per unit length of a flux line, which is shown to be strongly anisotropic. If, as seems likely, the pasta structure is imperfect, flux lines will be pinned and matter will behave as a good electrical conductor and flux decay times will be long. We describe some possible astrophysical manifestations of our results.
