摘要：Nuclear electron capture and the nuclear equation of state play important roles during the collapse
of a massive star and the subsequent supernova. The nuclear equation of state controls the
nature of the bounce which initially forms the supernova shock while electron capture determines
the location where the shock forms. Advances in nuclear structure theory have allowed a more
realistic treatment of electron capture on heavy nuclei to be developed. We will review how this
improvement has led to a change in our understanding of stellar core collapse, with electron capture
on nuclei with masses larger than 50 found to dominate electron capture on free protons,
resulting is significant changes in the hydrodynamics of core collapse and bounce. We will also
demonstrate the impact of a variety of nuclear equations of state on supernova shock propagation.
Of particular note is the interplay between the nuclear composition determined by the equation of
state and nuclear electron capture.
