EOS models#
JESTER provides multiple parametrizations for the neutron star equation of state, each with different physical assumptions and use cases.
Crust#
Tabulated low-density crust models (BPS, DH, SLy) used as the foundation for all core parametrizations.
Metamodel#
Taylor expansion of energy density around saturation density.
Metamodel + CSE#
Metamodel with speed-of-sound extrapolation to high densities.
Metamodel + peakCSE#
Metamodel with a Gaussian-peaked speed-of-sound extrapolation to high densities.
Spectral Decomposition#
4-parameter spectral expansion of the EOS.
