Abstract
We obtain a one parameter class of stationary rotating string cosmolog ical models of which the well-known Godel universe is a particular cas e. By suitably choosing the free parameter function, it is always poss ible to satisfy the energy conditions. The rotation of the model hinge s on the cosmological constant which turns out to be negative. String- dust distribution in Godel-type universes is also briefly discussed.
