  Recent studies show that accretion flows around weakly magnetic Neutron Stars
undergo multiple shocks, before reaching the surface of the star, which
contribute to the spectral and timing variabilities observed in the X-Rays.
Here, we report, for the first time, the spectral properties of a unified model
of shocked accretion flows around Neutron Stars, based on the Two-Component
Advective Flow paradigm. We compare our theoretical results with the X-Ray
spectral features of Z and Atoll sources, across different states. We also fit
RXTE/PCA spectra of Sco X-1 and 4U 1705-44 to show the potential application of
this new model.
