Wormhole solution in modified teleparallel-Rastall gravity and energy conditions
The possibility of static and spherically symmetric traversable wormhole
solution in modified teleparallel Rastall gravity (MTRG) in a non-diagonal
tetrad is investigated. Rastall assumption modifies the field equations and
energy-momentum conservation law. These modifications lead to different exact
asymptotically flat traversable wormhole solutions. By imposing different
constraints on modified energy-momentum conservation law, different exact
solutions are found and the obtained results for teleparallel Rastall gravity
(TRG), with specific choices of , are studied. It is shown that the
Rastall parameters have a key role in these models and in all of those exact
traversable wormhole solutions the null energy condition (NEC) and weak energy
condition (WEC) of matter or energy which has surrounded the wormhole are valid
at the throat of the wormhole and through the space time as well.Comment: 10 pages, 3 figures, submitted versio
