Hyperaccretion disks around neutron stars seem to exist in some GRBs. Such disks may also occur in type-II supernovae. We study the structure of a hyperaccretion disk around a neutron star. We divide the disk into two regions, which are called inner and outer disks. The outer disk is similar to that of a black hole and the inner disk has a self-similar structure. We first adopt a simple model, in which some microphysical processes in the disk are simplified, and then consider an elaborate model with more physical considerations about the thermodynamics and microphysics in the neutron star disk. Different from the disk around a black hole, the disk around a neutron star should eventually release the gravitational binding energy of accreted matter more efficiently.
