dc.description.abstract Black holes (BHs) are one of the most exotic objects found in the Universe. They fall into a class of astrophysical objects termed as compact objects. Apart from BHs, neutron stars (NSs) and white dwarfs (WDs) also fall into this classification. Such a name ‘compact’ is derived because, all these objects have very high values of compactness ratio (CR) which is defined as the ratio of the mass of the object to its radius. CR of compact objects are generally > 100 times than that of a normal Sun-like star. This high CR is responsible for their large surface gravitational potentials and hence, they exhibit a phenomena called accretion, which is the most efficient mechanism known till now, to convert the gravitational potential energy of the matter into radiation. The accretion flows around compact objects carry imprints of the nature of the central object. Hence, modelling of accretion flows is necessary. Based on this theme, we carried out our thesis work. en_US
