| Outline of Final Research Achievements |
The first direct gravitational wave (GW) signal, which has been interpreted as from a binary black hole, were observed in 14 September 2015. Therefore it is urgently necessary to theoretically understand "nature" related to GW for new era of GW astronomy.
The main purpose in this study had been to extract information of neutron stars (NSs) from GW of binary NS mergers.
Then we had obtained many important results. For example, the universal relations between the characteristic frequencies of GW and the physical quantities of NSs, have been found. By using the relations, in addition, we have constructed the powerful methods to decide the radii and an equation of state of NSs.
