摘要:

我们研究含有奇异物质的广义相对论致密星的结构。我们的研究是基于轴对称和静态形式主义,包括纯环形磁场。我们还研究了夸克-强子混合相的有限尺寸效应对磁星结构的影响。对于混合星,我们发现了一个特征性的磁场分布,它具有起源于夸克-强子混合相的不连续性。这些磁场分布将改变天体物理现象,例如冷却过程。

英文摘要:

We study structures of general relativistic compact stars with exotic matter. Our study is based on axisymetric and stationary formalism including purely toroidal magnetic field. We also study the finite size effects of quark-hadron mixed phase on structures of magnetars. For hybrid stars, we find a characteristic distribution of magnetic field, which has a discontinuity originated in the quark-hadron mixed phase. These distributions of magnetic field will change astrophysical phenomena, such as cooling processes.
