Impact of the neutron-star deformability on equation of state parameters

Understand

We use a Bayesian inference analysis to explore the sensitivity of Taylor expansion parameters of the nuclear equation of state (EOS) to the neutron star dimensionless tidal deformability ($\Lambda$) on 1 to 2 solar masses neutron stars.

• A global power law dependence between tidal deformability and compactness parameter (M/R) is verified over this mass region.
• To avoid superfluous correlations between the expansion parameters, we use a correlation-free EOS model based on a recently published meta-modeling approach.
• We find that assumptions in the prior distribution strongly influence the constraints on $\Lambda$.
