Description
A $G_2$ structure on a manifold can be defined in terms of the existence of a covariantly constant spinor, so naturally arise in SUSY preserving string compactifications. Such manifolds always admit extra structures, tied to the existence of families of nowhere vanishing vector fields. I will introduce these structures and some of their properties, and indicate the relevance for physics.
