Abstract:We present results from timing and spectral analysis of the HMXB X-ray pulsar IGR J19294+1816 observed using AstroSat during its recent Type-I outburst in October, 2019. AstroSat observations sampled the outburst at the decline phase right after the outburst peak. We carried out timing analysis on the light curves obtained using the Large Area X-ray Proportional Counter (LAXPC) instrument on board AstroSat and measured a spin period of 12.485065±0.000015 s. The peak in the power density spectrum (PDS) correspo… Show more
