Abstract

Type IIA flux compactifications with O6โ€planes have been argued from a four dimensional effective theory point of view to admit stable, moduli free solutions. We discuss in detail the ten dimensional description of such vacua and present exact supersymmetric solutions in the case when the O6โ€charge is smoothly distributed: the geometry is Calabiโ€Yau and the dilaton is constant. In the localized case, the solution is a halfโ€flat, nonโ€Calabiโ€Yau metric but still with constant dilaton. Finally, using the ten dimensional description we show how all moduli are stabilized and reproduce precisely the results of de Wolfe et al. [arXiv:hepโ€th/0505160]. This talk is based on [arXiv:hepโ€th/0607223].

## Abstract We review some of the features of Type IIA compactifications in the presence of fluxes. In particular, the case of __T__^6^/(ฮฉ (โ€1) ฯƒ) orientifolds with RR, NS and metric fluxes is considered. This has revealed to possess remarkable properties such as vacua with all the closed string mo

## Abstract We summarize and extend our work on flux vacua attractors in generalized compactifications. After reviewing the attractor equations for the heterotic string on SU(3) structure manifolds, we study attractors for N = 1 vacua in type IIA/B on SU(3) ร— SU(3) structure spaces. In the case of
