Direct mapping of tidal deformability to the iso-scalar and iso-vector nuclear matter parameters

Understand

Background: The equations of state (EoSs) which determine the properties of neutron stars (NSs) are often characterized by the iso-scalar and iso-vector nuclear matter parameters (NMPs).

• Recent attempts to relate the radius and tidal deformability of a NS to the individual NMPs have been inconclusive.
• These properties display strong correlations with the pressure of NS matter which depends on several NMPs.
• The knowledge of minimal NMPs that determine the NS properties will be necessary to address any connection between NS properties (e.g., tidal deformability) and that of finite nuclei.
