I have a scientific background in materials science. However this is one type of material that we don't exactly learn about! Let's say you have a neutron star approaching a comparable mass black hole. As the neutron star approaches the event horizon for such a comparable black hole, tidal forces increase extremely quickly. Can the neutron star's structure be disrupted by tidal forces outside the horizon? If it can, what will the fragments look like and what will be their properties, and how will they differ from that of a bulk neutron star? indeed, what are the material properties (electrical and thermal conductivity as well as their optical, magnetic and mechanical properties) of a bulk neutron star? Can neutron stars be even considered solids?
