Neutron stars in mimetic gravity

In this paper, a modified version of the hydrostatic equilibrium equation based on the mimetic gravity in the presence of perfect fluid is revisited. By using the different known equation of states, the structural properties of neutron stars are investigated in general relativity and mimetic gravity. Comparing the obtained results, we show that, unlike general relativity, we can find the appropriate equation of states that support observational data in the context of mimetic gravity. We also find that the results of relativistic mean-field-based models of the equation of states are in better agreement with observational data than non-relativistic models.

Automated summary

This paper investigates the structural properties of neutron stars in the context of general relativity and mimetic gravity, and finds that the appropriate equation of states can be found in the framework of mimetic gravity to support observational data. It also shows that the results of relativistic mean-field-based models are in better agreement with observational data than non-relativistic models.
