Outline of Final Research Achievements

In order to constrain the radius of neutron stars by using the ASTRO-H (Hitomi) satellite, we performed necessary improvements and tests for X-ray detectors onboard ASTRO-H. We succeeded in demonstrating the required performances, such as the energy resolution of 4.9 eV by Micro Calorimeter. We improved high counting capability of the data acquisition system, required for neutron star observations. Despite of the early termination of the satellite, we have succeeded in obtaining technology to measure the radius of neutron stars, precisely. This enables us to constrain the EOS of nuclear matter by future missions.
By using archival data, we detected characteristic structure in a spectrum during an X-ray burst and proposed a new method to estimate the gravitational redshift at the neutron star surface. We advanced development of new detectors for future X-ray and gamma-ray missions, such as a semiconductor sensor for high counting observation and a detector to measure X-ray polarization.
