Abstract: In this talk, I will cover many of the theoretical aspects of generating binary neutron star initial data. This will include a discussion of the different formalisms used, as well as the different numerical approaches. Comparisons to black holes will include a discussion of why neutron stars often require different techniques due to both their hydrodynamic properties as well as the existence of a stellar surface, the latter of which presents a surprising challenge in developing highly accurate numerical schemes. The talk will also discuss the typical physical assumptions made about NS masses, spins, and equations of state (the relationship between pressure and density inside the neutron star), as well as the physical effects that have proven to be more difficult to model self-consistently, in particular the inclusion of magnetic fields.
