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 σωρ\sigma\omega\rho mesons, and compare the results with the ones obtained with the inclusion of the strangeness hidden ϕ\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 Gv(ψˉγμψ)G_v(\bar{\psi}\gamma^\mu\psi). Magnetic fields are taken into account via chaotic magnetic field approximation.
