Abstract
In the present work we have searched the existence of the late time acceleration of the universe with string fluid as source of matter in anisotropic Heckmann-Schucking space-time by using 287 high red shift \((0.3 \leq z\leq1.4)\) SN Ia data of observed absolute magnitude along with their possible error from Union 2.1 compilation. It is found that the best fit values for \((\varOmega_{m})_{0}\), \((\varOmega_{\varLambda})_{0}\), \((\varOmega_{\sigma })_{0}\) and \((q)_{0}\) are 0.2820, 0.7177, 0.0002 & −0.5793 respectively. Several physical aspects and geometrical properties of the model are discussed in detail.
