Long Time Variable Source J141648.7+522558
Abstract
We analyzed X-ray archival data of J141648.7+522558. The region is observed by XMM-Newton (2000) and Chandra (2002 and 2014). The source has a southern companion with a 30 arc sec separation, J141649.4+522531. Both X-ray sources seem to have bright elliptical counterparts coinciding at their X-ray peak. By comparing the fluxes we observe the southern source has a consistent emissivity at 3 different epochs. The source J141649.4+522531 is observed to have a steady emission and a consistent flux value of about F_X = 7 × 10^{-14} ergs s^{-1} cm^{-2} over 14 years. On the other hand, J141648.7+522558 has an emission of a flux value F_X = 3.5 × 10^{-14} ergs s^{-1} cm^{-2} in the year 2000 but not detectable in 2002 and 2014 observations by Chandra. The nature of this flux variability and the underlying physics is discussed by considering possible mechanisms to affect the emission dramatically.
