Testing universal relations of neutron stars with a nonlinear matter-gravity coupling theory

Sham, Y. -H., Lin, L. -M., Leung, P. T.

Understand

Due to our ignorance of the equation of state (EOS) beyond nuclear density, there is still no unique theoretical model for neutron stars (NSs).

  • It is therefore surprising that universal EOS-independent relations connecting different physical quantities of neutron stars can exist.
  • Lau et al.
  • [ApJ, 714, 1234 (2010)] found that the frequency of the $f$-mode oscillation, the mass, and the moment of inertia are connected by universal relations.
