Description

In this talk I will discuss the application of the Witten-Sakai-Sugimoto model for holographic QCD to neutron star matter. I will begin with a brief review of the important features of the model, including the recent theoretical advances provided by Kovensky and Schmitt in allowing for isospin asymmetric homogeneous baryonic matter. I will then describe how this can be used to construct the neutron star equation of state entirely from holography, including a dynamical computation of the crust-core transition. Finally, I will show that despite our version of the model containing only three free parameters, it is able to account for stars which simultaneously meet the current astrophysical constraints on mass, radius and tidal deformability. This talk is based on work in collaboration with Andreas Schmitt and Nicolas Kovensky.
