Chuck Horowitz: Physics of the neutron star crust and its breaking strain

In accreting Neutron Stars the new crust formed is a perfect crystal with some impurities, which could increase pycnocuclear reactions. Perhaps this provides the heat needed to explain superburst ignition (see Cumming talk).

NS shear modulus seems to be independent of impurities.

NS nuclear pasta shear viscosity does not depend on the pasta shape.

NS crust does not fracture.

Liliana asks: If NS does not break, where are the star faults (star quake sources) located?
