Unveiling a universal relationship between the f(R) parameter and neutron star properties

Understand

In recent years, modified gravity theories have gained significant attention as potential replacements for the general theory of relativity.

• Neutron stars, which are dense compact objects, provide ideal astrophysical laboratories for testing these theories.
• However, understanding the properties of neutron stars within the framework of modified gravity theories requires careful consideration of the presently known uncertainty of equations of state (EoS) that describe the behavior of matter at extreme densities.
• In this study, we investigate three realistic EoS generated using a relativistic mean field framework, which covers the currently known uncertainties in the stiffness of neutron star matter.
