Likelihood Constraints

JESTER supports multiple observational constraints from multi-messenger astronomy to constrain the neutron star equation of state. These likelihoods can be combined in Bayesian inference.

Available Constraints

Gravitational Waves

Binary neutron star merger observations (GW170817, etc.).

Gravitational Wave Constraints

NICER

X-ray timing constraints on mass and radius (PSR J0030+0451, PSR J0740+6620).

NICER Constraints

Nuclear Experiments (ChiEFT)

Chiral effective field theory constraints on low-density nuclear matter.

Nuclear Experiments (ChiEFT)

Radio Timing

High-precision pulsar mass measurements.
