Neutron Star Astrochemistry

[Anchovyforestbane]

It is somewhat common for particularly dense neutron stars to form a solid crusts, much like a planet's, with any matter that happens to be around them. At these densities, the neutronium between the crust and the center of mass forms a sort of mineraloid structure (known as "nuclear pasta"). I've been curious as to the chemical properties of this as well as the mechanisms responsible. Does the composition of a neutron star's crust effect the formation of nuclear pasta in any way? For example, would it make a difference if the neutron star formed its crust out of ethane or cyclopropenylidene? What if you threw some magnesium or caesium into the equation? I'm not limiting discussion to these, but they're simply examples to work with (presuming that there would be any difference whatsoever, that is).
