  In the present study we have proposed a new model of an anisotropic compact
star which admits the Chaplygin equation of state. For this purpose, we
consider Buchdahl ansatz. We obtain the solution of proposed model in closed
form which is non-singular, regular and well-behaved. In addition to this, we
show that the model satisfies all the energy conditions and maintains the
hydrostatic equilibrium equation. This model represents compact stars like PSR
B0943+10, Her X-1 and SAX J1808.4-3658 to a very good approximate.
