Abstract

In this paper, we analyzed pulse profiles of Swift J1626.6+5156 using the lightcurves from RXTE-PCA observations between MJD 53724 (just after the outburst) and MJD 55113 and a Chandra-ACIS dataset on MJD 54897 with a 20 ks exposure. We found that pulse profiles show morphological variations and pulsations do not cease even similar to 1200 days after the outburst. Despite these variations, we did not find any significant variation in the pulsed fraction with decreasing X-ray flux.
