Structure and composition of the inner crust of neutron stars from Gogny interactions

The detailed knowledge of the inner crust properties of neutron stars might be important to explain different phenomena such as pulsar glitches or the possibility of an -process site in neutron star mergers. It has been shown in the literature that quantal effects like shell correction or pairing ma...
