We investigate the effects of the leading tadpole potentials of 10Dtachyon-free non-supersymmetric strings in warped products of flat geometriesof the type M(p+1) x R x T(10-p-2) depending on a single coordinate. In theabsence of fluxes and for p<8, there are two families of these vacua for theorientifold disk-level potential, both involving a finite internal interval.Their asymptotics are surprisingly captured by tadpole-free solutions,isotropic for one family and anisotropic at one end for the other. In contrast,for the heterotic torus-level potential there are four types of vacua. Theirasymptotics are always tadpole-dependent and isotropic at one end lying at afinite distance, while at the other end, which can lie at a finite or infinitedistance, they can be tadpole-dependent isotropic or tadpole-free anisotropic.We then elaborate on the general setup for including symmetric fluxes, andpresent the three families of exact solutions that emerge when the orientifoldpotential and a seven-form flux are both present. These solutions include apair of boundaries, which are always separated by a finite distance. In theneighborhood of one, they all approach a common supersymmetric limit, while theasymptotics at the other boundary can be tadpole-free isotropic, tadpole-freeanisotropic or again supersymmetric. We also discuss corresponding cosmologies,with emphasis on their climbing or descending behavior at the initialsingularity. In some cases the toroidal dimensions can contract during thecosmological expansion.
