Influences Of Fermionic Dark Matter On The Structure And The Cooling Properties Of Neutron Stars

Neutron star, a new compact star, is the massive star at the stage of the late evolution,after the supernova explosion, and formed at its center, and it is one of the high-temperature and high-density stars that can be observed at present. Neutron star macroscopic properties provides a natural laboratory research for compact matter. However,due to the lack of information of the compact matter, there are many uncertain factors to neutron stars, such as the matter, the structure and the cooling properties of neutron stars.Dark matter, a possible constituent of neutron stars, has great influences on the structure,the evolution, the thermal radiation, the magnetic fields and observations of neutron stars.At present, many scholars have focused on the studies about the influences of dark matter on the structure of neutron stars. However, based on these studies, we will continue to explore the influences of dark matter on the cooling properties of neutron stars.There are four parts in the work. The historical review and research progresses of dark matter, including the formation process, the classification and the properties of dark matter,and several dark matter models are introduced in Part One. The formation, the structure and the related theories of neutron stars, containing the relativistic mean field theory(RMFT), the cooling theories, TOV equations and so on are given in detail in Part Two.The RMFT is adopted to study the influences of fermionic dark matter on the equation(EoS) and the mass-radius relation of neutron stars in weak and strong interaction in the dark-matter admixed neutron star(DANS) model in Part Three. And effects of femionic dark matter on the neutrino emission, the luminosity and the cooling curves of neutron stars are studied in Part Five. At last, conclusions and expectations are given.
