چکیده
|
There are some gravitational theories in which the ordinary energy–momentum conservation law is not valid in the
curved space–time. Rastall gravity is one of the known theories in this regard, which includes a non-minimal coupling between
geometry and matter fields. Equipped with the basis of such theory, we study the properties of traversable wormholes with flat
asymptotes. We investigate the possibility of exact solutions by a source with the baryonic matter state parameter. Our survey
indicates that Rastall theory has considerable effects on the wormhole characteristics. In addition, we study various case studies
and show that the weak energy condition may be met for some solutions. We also give a discussion regarding traversibility of
such wormhole geometry with phantom sources.
