4. Neutron stars and nuclear matter parameters

Neutron stars can be suitable laboratory to see the physics under the ultra-high density region. The direct observations of neutron stars help us to understand the nuclear matter properties and equation of state. On the other hand, the terrestrial nuclear experiments directly reveal such properties especially around the saturation density, which are strongly coupled with not only the crust...

23. Obtaining the neutron star gravitational mass limit in the frame work of the LOCV method

Hamidreza Moshfegh (University of Tehran)

Using the lowest order constrained variational method (LOCV) we calculate the equation of state of pure neutron matter (PNM) as well as the charge neutral (n,p,e,μ) matter in beta equilibrium with AV18 two-body nucleon-nucleon interaction supplemented by a microscopic three-body force. The neutron star gravitational mass limit obtained with this interaction is 2.62 M⊙ for PNM and 2.41 M⊙ in...

148. Electromagnetic signals from bare strange stars

Dr Giulia Pagliaroli (INFN - LNGS)

Strange stars with a crystalline color superconducting crust can sustain large shear stresses, supporting torsional oscillations of large amplitude. Moreover if a bare quark matter surface is present electrons spill in the star exterior forming an electromagnetically bounded atmosphere hundreds of Fermi thick. We investigate the electromagnetic signature connected with a torsional...

30. Inhomogeneous structures of neutron star crust and mechanical properties

We investigate inhomogeneous structures and properties of low-density nuclear matter by a relativistic mean-field approach with a fully three-dimensional geometry [1]. By avoiding usage of Wigner-Seitz approximation, we can discuss a priori the structure of matter. We show that nuclear droplets form a body-centered-cubic (bcc) lattice at lower densities. With increasing density, it changes to...
