Magnetized Unified RMF Equation of State for Cold Neutron Star

Unified outer crust+ inner crust + core equation of state for magnetized npe beta-equilibrated matter, calculated within the RMF formalism using the NL3wr model [1,2]. We consider magnetic field between 10^16 G and 10^18 G.

The outer crust was calculated using the tool [3].

The file NL3wr_magnetized_outer+inner+core_AMM.txt is calculated including the contribution of the anomalous magnetic moment of the nucleons, while the file NL3wr_magnetized_outer+inner+core.txt does not include that contribution.

Each file is composed of 11 columns which contain, in order:

1) The magnetic field in G

2) The total number density (nucleons + electrons) in fm^-3

3) The total energy density in fm^-4

4) The component of the total pressure parallel to the magnetic field in fm^-4

5) The baryonic chemical potential in MeV

6) The mesonic field contribution to the pressure in fm^-4

7) The baryonic contribution to the parallel component of the pressure in fm^-4

8) The baryonic number density in fm^-3

9) The squared speed of sound

10) The component of the total pressure normal to the magnetic field in fm^-4

11) The total magnetization divided by the magnetic field
