摘要: We report recent XMM-Newton investigations of PSR J1836+5925, the "next Geminga," which determined an X-ray pulsation of ~ 173.3 ms. Its X-ray periodicity is consistent with the y-ray ephemeris at the same epoch. The X-ray folded light curve has a sinusoidal structure that is different from the double-peaked y-ray pulse profile. We have also analyzed the X-ray phase-averaged spectra which shows that the X-ray emission from PSR J1836+5925 is thermal dominant. This suggests that the X-ray pulsation mainly originates from the modulated hot spot on the stellar surface. 出版者: United States 出版日期: 2014-09-20 出處: Astrophysical journal.
