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

http://arxiv.org/abs/1909.05400


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 $\phi$ 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.
