Magnetized Rotational Neutron Stars and Mass-radius Relation

DOI Open Access

Description

We calculate radii and masses of neutron stars for various EoSs using a perturbative approach. We also calculate increased masses due to magnetic fields. Moreover, we calculate the radius of a neutron star as a function of its increased total mass due to rotation. As for the EoSs, we adopt various kinds of models in relativistic mean field (RMF) theory. We calculate mass-radius relations (MR relations) using 5 hadronic EoSs. We have obtained the result that the total masses are over twice the solar mass for all 5 hadronic EoSs in the presence of magnetic fields together with rotation.
