Document Abstract
We study the motion of pinning of superfluid vortices inside the inner crust of neutron star. The pinning
occurring in NS crust is assumed to be of certain lattice orientation of an ideal body centered cubic lattice. Here,
we tend to solely examine the interaction between nuclei within the vortex line for Nuclear and Interspatial pinning
withinfive different regions of superfluid crust. The angular momentum for the superfluid neutronsis in the form of
array of quantized vortices. Furthermore, when these vortices are pinned to the nuclear lattice, it restricts the
superfluid from spinning down along with storing the angular momentum which when released causes pulsar
glitches. During this paper, we tend to investigate the role of drag parameter, capture radius and coherence length
for vortex-nucleus interaction throughout the two pinning actions and study the variation in effective pinning
energy for the five different regions within superfluid crustwith respect to pinning energy per pinning site.
