Exploring physics of dense matter using gravitational waves
from binary neutron star merger

Abstract:
Binary neutron star mergers are quite interesting phenomena
in the universe. They are ones of the most promising sources
of gravitational waves. The information carried by gravitational
waves would contain dynamical responses of neutron stars,
which can be used to explore the physics of dense matter.
In this sense, binary neutron star mergers may be regarded as
a cosmological collider or laboratory to explore the fundamental
physics. To study binary neutron star mergers, numerical relativity
is the most viable approach and recent advances in this field
have yielded a number of important results, such as extraction
of information of radius from gravitational waves, a possible way
to constrain the composition of the neutron star matter, and
importance of the equation of state of dense matter on the origin
of heavy elements. In this talk, starting from brief discussions on
the relationship among structure of neutron star, equation of state,
and nuclear parameters like symmetry energies, I will review
recent developments and discuss future prospects.
