We study how the magnetic field and non-standard vector channels affect hadronic, quark and hybrid stars. In the hadronic phase, we use the QHD model, with its standard \(\sigma \omega \rho \) mesons, and compare the results with the ones obtained with the inclusion of the strangeness hidden \(\phi \) meson. In the quark phase, we use the standard SU(3) NJL and compare the results with the version that takes into account the vector channel \(G_v({\bar{\psi }}\gamma ^\mu \psi )\). Magnetic fields are taken into account via chaotic magnetic field approximation.

向量通道在不同类别的(非)磁化中子星中的作用

我们研究磁场和非标准矢量通道如何影响强子,夸克和混合星。在强子力阶段,我们使用QHD模型及其标准的\(\ sigma \ omega \ rho \)介子,然后将结果与包含隐匿的\(\ phi \)介子的结果进行比较。在夸克阶段,我们使用标准SU(3)NJL并将结果与​​考虑矢量通道\(G_v({\ bar {\ psi}} \ gamma ^ \ mu \ psi \\)的版本进行比较。。通过混沌磁场近似将磁场考虑在内。
