Abstract
Some new class of Chaplygin wormholes are investigated in the framework of a Chaplygin gas with the equation of state [Formula: see text]. Since empty spacetime (p = ρ = 0) does not follow Chaplygin gas, so the interior Chaplygin wormhole solutions will never be asymptotically flat. For this reason, we have to match our interior wormhole solution with an exterior vacuum solution, i.e. Schwarzschild solution at some junction interface, say r = a. We also discuss the total amount of matter characterized by Chaplygin gas that supplies fuel to construct a wormhole.
