摘要:
The tunnel-like structures proposed by Morris and Thorne are explored in this study by using f(R, T) framework. The solutions of static wormhole, supported by the matter possess van der Waals equation of state, are derived by two possible schemes. We have explored the shape function and energy conditions including null, weak, strong and dominant conditions. For this purpose, we used the equation of state p(r) = -alpha rho(2) in first scheme and a numerical technique in second scheme. Also, the radius of the wormhole's throat is calculated, within which the energy conditions are satisfied. We have also deliberated the graphical illustrations of all the solutions.
