Outline of Final Research Achievements

Neutron star has been interesting to many physicists for a long time, since it has many interesting and unknown properties such as the rapid rotation and huge magnetic field as well as the high density profile. Moreover, the study of neutron stars is an essential research subject, which is related to the understanding of mechanism of the supernova explosion, creation of heavy elements like gold, the gravitational wave radiation and matter state at high density. I studied this issue mainly from particle physics side. I obtained several results such as the construction of equations describing the mass and radius of the star, the relation between huge magnetic field and chiral symmetry which is an important property for elementary particles, and dark matter capture in neutron stars. I reported these in various workshops, meetings and conferences as well as the scientific journals.
