Article Description

In this article, we present a family of static and spherically symmetric wormholes in Rastall gravity. The unique characteristics of this modified theory is the violation of the local conservation of the energy-momentum tensor. These wormholes are supported by applying a specific equation of state for matter satisfying the tracelessness constraint [Kar and Sahdev: Phys. Rev D {\bf 52}, 2030 (1995)]. Next, we impose some restrictions on the redshift function, and solve the field equations analytically for a classical traversable wormholes. Finally, we investigate some issues concerning the energy conditions and volume integral quantifier in these time-interdependent geometries.
