Low Mass X-ray Binaries (LMXBs) often exhibit a number of X-ray variability signatures that get reprocessed into the UV/optical band. We investigate X-ray to optical reprocessing in a few LMXB systems and detect interesting reprocessing signatures that indicate the presence of evolving structures on the accretion disk. I will further discuss disk wind emission scenarios and its possible correlation to the luminosity state in neutron star X-ray binaries. LAXPC on-board ASTROSAT presents innumerable prospects for observing rapidly rotating, accreting neutron star binaries, which are promising sources of detectable Gravitational Wave (GW) emission. I will discuss prospects of binary orbital parameter measurements that will enable current generation GW detectors to carry out a fully coherent search for GW that is computationally optimized.
