Query: Neutron Stars in Mimetic Gravity   The investigation of gravitational waves and other observational evidence
confirm the possibility of massive neutron stars. At the same time in order to
describe the internal structure of neutron stars, there are theoretical
challenges to the suitable gravitational model and the proper equation of
state. Here, a modified version of hydrostatic equilibrium equation based on
the mimetic gravity in the presence of perfect fluid is introduced. Meanwhile,
using different candidates of state equation, the structure properties of
neutron stars are investigated. Unlike general relativity, in the context of
mimetic gravity, we find an appropriate EoS that supports observational data.
