Revealing Magnetars Based on Studies on Proton Cyclotron Absorption Line in Super-Strong Magnetic Field

我使用日本的X射线卫星朱雀号对具有~10^ G“磁星”的高磁化中子星进行了观测研究<15>。为了探测质子回旋共振特征和直接测量磁场强度，我对三颗活跃期磁星进行了观测和分析。虽然我在X射线光谱中没有发现任何特征，但我在弱爆发的X射线光谱中发现了硬X射线成分。此外，还发现了活跃相的X射线谱比平静相的X射线谱更暗的可能性。

I performed observational studies of higly magnetized neutron stars with～10^<15> G "Magnetars" using Japanese X-ray satellite Suzaku. In order to detect proton cyclotron resonance featrures and directly measure a magnetic field strength, I performed observations and analyses of three magnetars in active phases. Although I did not find any features in X-ray spectra, I discovered hard X-ray components in the X-ray spectra of weak bursts. In addition, I found a possibility that X-ray spectra in active phases are hader than those in quiet phases.
