We report X-ray data analysis results obtained from Chandra, XMM-Newton,NuSTAR and Swift observations of PSR J2032+4127 taken before, during, and afterthe periastron on 2017 November 13. We found the first clear evidence of achange in the X-ray spectral index over the passage period, thanks to a broadand sensitive spectral coverage by XMM-Newton and NuSTAR. We analysed the jointXMM-Newton and NuSTAR observation epochs with power-law and broken power-lawmodel. We have obtained change in spectral parameters before and after theperiastron passage for both models. The spectra get softened after the passage.The evolution of the spectral index and break energy before and after theperiastron may indicate a change in the physical state of shock-acceleratedelectrons.
