Dilatonic black holes in heterotic string theory

We obtain the spherically symmetric black hole solutions with dilatonic charge in heterotic string theory with curvature-squared corrections in arbitrary d spacetime dimensions (previously this result was only known for d=4). We compute some of their physical properties, like mass, temperature and entropy. We derive the tensorial perturbations to this metric and their respective potential, from which we study their stability. We compare these with our previous results for nondilatonic string-corrected black holes.
