heal.abstract	We study the dimensional reduction of the N{script} = 1, ten-dimensional Heterotic Supergravity to four dimensions, at leading order in α′, when the internal space is a nearly-Kähler manifold. Nearly-Kähler manifolds in six dimensions are all the non-symmetric coset spaces and a group manifold. Here we reduce the theory using as internal manifolds the three six-dimensional non-symmetric coset spaces, omitting the case of the group manifold in the prospect of obtaining chiral fermions when the gauge fields will be included. We determine the effective actions for these cases, which turn out to describe N{script} = 1 four-dimensional super-gravities of the no-scale type and we study the various possibilities concerning their vacuum. © 2009 WILEY-VCH Verlag GmbH & Co.
