A New Open-Source Nuclear Equation of State Framework based on the Liquid-Drop Model with Skyrme Interaction

Understand

The equation of state (EOS) of dense matter is an essential ingredient for numerical simulations of core-collapse supernovae and neutron star mergers.

• The properties of matter near and above nuclear saturation density are uncertain, which translates into uncertainties in astrophysical simulations and their multi-messenger signatures.
• Therefore, a wide range of EOSs spanning the allowed range of nuclear interactions are necessary for determining the sensitivity of these astrophysical phenomena and their signatures to variations in input microphysics.
• We present a new set of finite temperature EOSs based on experimentally allowed Skyrme forces.
