Spherically symmetric gravitational collapse in Einstein Gauss-Bonnet theory

This paper deals with spherically symmetric gravitational collapse of inhomogeneous perfect fluid in Einstein Gauss-Bonnet gravity. The physical quantities have been plotted in the EGB gravity. The Ricci Scalar and Kretschmann scalar have been determined to study the curvature singularity. The shell focusing curvature singularities are generated at last stage of gravitational collapse of object. The formation of singularity and apparent horizon depends on the initial data. Also, the energy conditions have been discussed for the reasonable energy momentum tensor. The presence of GB coupling constant a modifies the structure of singularity and formation of apparent horizon.
