Description
Smooth solutions of the Strominger system with non vanishing flux, non-trivial instanton
and non-constant dilaton based on the quaternionic Heisenberg group are constructed. It is shown that through appropriate contractions
the solutions found in the $G_2$-heterotic case converge to the heterotic solutions on 6-dimensional inner non-K\"ahler
spaces previously found and, moreover, to new heterotic solutions with non-constant dilaton in dimension 5.
All the solutions satisfy the heterotic equations of motion up to the first order of \alpha^{\prime}.
