Precessing black hole - neutron star binary systems

      

In order to construct accurate gravitational waves models for binaries,

numerical relativity simulations with a wide range of physical parameters

are required. One important parameter is the spin orientation of both

objects in the binary system. In our research we focus on the effects of

precession on the gravitational waves. We construct initial data using the

Elliptica code for a black hole - neutron star binary system with spin

orientations that result in precession. We then study the inspiral of the

binary using the BAM code. In this talk, we explain the initial data

construction within Elliptica. We then present some preliminary results of

the evolution, such as gravitational waves, trajectories and constraints for

a precessing black hole - neutron star binary system.
