Comparison of properties of the simplest neutron stars in three RMF models

We study some properties of the simplest neutron stars ( NSs) in the Glendenning - Moszkowski ( GM) model, the hybrid derivative coupling ( HD) model and the Zimanyi - Moszkowski ( ZM) model in the framework of relativistic mean. eld ( RMF) theory with and without the interaction by exchanging the d- meson. We show that the maximal mass of the NSs becomes smaller, but the redshift becomes larger from the GM model to the HD model, then to the ZM model. The interaction with the d- meson exchange enlarges the maximal mass of neutron stars, increases the relative population of charged particles ( proton, electron and muon) and descends the relative population of neutron.Physics, MultidisciplinarySCI(E)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)0ARTICLE82837-28402
