Role of vector channel in different classes of (non) magnetized neutron stars

Abstract

We study how the magnetic field and non-standard vector channels affect hadronic, quarkionic and hybrid stars. In the hadronic phase, we use the QHD model, within its standard $\sigma \omega \rho$ mesons, and compare the results with the ones obtained with the inclusion of the strangeness hidden $\varphi$ 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.
