Research Abstract |
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.
