Abstract
We show that the supertube configurations exist in all supersymmetric type IIA backgrounds which are purely geometrical and which have, at least, one flat direction. In other words, they exist in any spacetime of the form ℝ1,1 × ℳ8, with ℳ8 being any of the usual reduced holonomy manifolds. These generalized supertubes preserve 1/4 of the supersymmetries preserved by the choice of the manifold ℳ8. We also support this picture with the construction of their corresponding family of IIA supergravity backgrounds preserving from 1/4 to 1/32 of the total supercharges.
