Description
Importance of the late time accelerated expansion of the Universe in the study of astrophysical phenomena in local galactic-scales is highlighted. From the principle of conserved Hamiltonian of the test particle motion a three dimensional Newtonian analogous potential has been obtained in spherical geometry corresponding to Schwarzschild de Sitter space time, that reproduces almost all of the GR features in its entirety with remarkable accuracy. Applying the derived analogous potential the influence of cosmological constant on Bondi accretion rate has been demonstrated.
