Self-adjoint wave equations for dynamical perturbations of self-gravitating fields
O. Sarbach, M. Heusler, O. Brodbeck
It is shown that the dynamical evolution of linear perturbations on a static space-time is governed by a constrained wave equation for the extrinsic curvature tensor. The spatial p…

The generalization of the Regge-Wheeler equation for self-gravitating matter fields
Othmar Brodbeck, Markus Heusler, Olivier Sarbach
It is shown that the dynamical evolution of perturbations on a static spacetime is governed by a standard pulsation equation for the extrinsic curvature tensor. The centerpiece of…

On rotational excitations and axial deformations of BPS monopoles and Julia-Zee dyons
M. Heusler, N. Straumann, M. Volkov
It is shown that Julia-Zee dyons do not admit slowly rotating excitations. This is achieved by investigating the complete set of stationary excitations which can give rise to non-v…
