X-ray study of variable gamma-ray pulsar PSR J2021+4026
Abstract
Variable gamma ray pulsar PSR J2021+4026 showed a glitch around 2011, October 16. After the glitch, the pulsar stayed a low gamma ray flux state for 3 years, and then returned to the state before the glitch. To investigate any change in the X-ray emissions in low-gamma-ray flux state and after the relaxation, we analyze XMM-Newton data. We find no significant change in the X-ray emission in the two stages. We fit the X-ray light curve with the heated polar cap model, and discuss half hemisphere of the magnetosphere is less active.
