Galactic Halo Wormhole Solutions in f ( T )‎ Gravity

Abstract EN

The proposal of galactic halo region is based on the idea that dark halos contain some characteristics needed to support traversable wormhole solutions.

We explore wormhole solutions in this region in the framework of generalized teleparallel gravity.

We consider static spherically symmetric wormhole spacetime with flat galactic rotational curves and obtain expressions of matter components for nondiagonal tetrad.

The effective energy-momentum tensor leads to the violation of energy conditions which may impose condition on the normal matter to satisfy these conditions.

We take two well-known f ( T ) models in exponential and logarithmic forms to discuss wormhole solutions as well as the equilibrium condition.

It is concluded that wormhole solutions violating weak energy condition are obtained for both models with stable configuration.
