Eikonal quasinormal modes and shadow of string-corrected d-dimensional black holes
We compute the quasinormal frequencies of d-dimensional spherically symmetric black holes with leading string α′ corrections in the eikonal limit for tensorial gravitational perturbations and scalar test fields. We find that, differently than in Einstein gravity, the real parts of the frequency are...
