Abstract
We present a class of exact solutions of Einstein's gravitational-field equations describing spherically symmetric and static anisotropic stellar-type configurations. The solutions are obtained by assuming a particular form of the anisotropy factor. The energy density and both radial and tangential pressures are finite and positive inside the anisotropic star. Numerical results show that the basic physical parameters (mass and radius) of the model can describe realistic astrophysical objects such as neutron stars.
