| Abstract: | We present here results from our search for X-ray pulsations of the neutron star in the low mass X-ray binary EXO 0748–676 at a frequency near the burstoscillation frequency of 44.7Hz. Using the observations made with the Proportional Counter Array onboard the Rossi X-ray Timing Explorer, we did not find any pulsations in the frequency band of 44.4Hz to 45.0Hz and obtained a 3σ upper limit of 0.47% on the pulsed fraction for any possible underlying pulsation in this frequency band.We also discuss the importance of EXO 0748–676 as a promising source for the detection of Gravitational Waves. |
