Description

We apply magnetic fields of the order of 10^17 G and 10^18 G to nuclear matter, and study its influence on the symmetry energy and its slope. We also study the effects caused by the inclusion of anomalous magnetic moments to these quantities. Then, we investigate the effects caused by strong magnetic fields on the properties of compact objects, composed by hadronic matter in β-equilibrium, interacting via (σ − ω − ρ) mesonic fields. To do so we use the non-linear Walecka model and some parametrizations normally found in the literature. Submitting hadronic matter to magnetic fields of the order of 10^17 G and 10^18 G, we also study the effects of the inclusion of the anomalous magnetic moment to the equations of state and corresponding mass-radius relation. We also study the effects of the inclusion of a term that takes into account the interaction between the ω and ρ mesons subject to strong magnetic fields. At last we compare the obtained curves for the theoretical models with three known binary systems observation data.
