In this thesis, RXTE observations of 4U 1907+09 are presented. Timing
analysis of these data sets have yielded quasi periodic oscillations
(QPOs) at orbital phases corresponding to the two flares in every orbital
period. Known continuous spin down trend and QPO behaviour at the
flares strongly suggest that a transient accretion disk occurs at the
flares. Our
findings strongly suggested that neutron star passes through the
equatorial wind of Be companion star. During these passages a
transient disk forms around Be neutron star.
