Impact of hyperon mixing on neutron star structure based on Skyrme-type equations of state: Systematic analysis of $Λ N N$ and $ΛΛ N$ three-body forces with Bayesisan inference

Taeho Lee, Yoonhak Nam, Kazuyuki Sekizawa

We study hyperonic density-dependent three-body effects in cold neutron-star matter using a Skyrme energy-density-functional framework. In beta-equilibrated $n p e μ Λ$ matter, the eff…

Data-driven exploration of the neutron $^{3} P_{2}$ pairing gap using Cassiopeia A neutron star observational data: Direct $χ^{2}$ minimization

Yoonhak Nam, Kazuyuki Sekizawa

The rapid cooling observed in the Cassiopeia~A neutron star (Cas~A NS) is one of the most stringent tests for neutron-star cooling theory. While Cooper-pair breaking and formation…
