  Superfluid dilute neutron matter and ultracold gas, close to the unitary
regime, exhibit several similarities. Therefore, to a certain extent, fermionic
ultracold gases may serve as emulators of dilute neutron matter, which forms
the inner crust of neutron stars and is not directly accessed experimentally.
Quantum vortices are one of the most significant properties of neutron
superfluid, essential for comprehending neutron stars' dynamics. The structure
and dynamics of quantum vortices as a function of pairing correlations'
strength are being investigated experimentally and theoretically in ultracold
gases. Certain aspects of these studies are relevant to neutron stars. We
provide an overview of the characteristics of quantum vortices in s-wave-type
fermionic and electrically neutral superfluids. The main focus is on the
dynamics of fermionic vortices and their intrinsic structure.
