Abstract
The scalar wave equation is considered in the background of a charged Vaidya metric in double null coordinates describing a non-stationary charged black hole with varying mass and charge . The resulting time-dependent quasinormal modes are presented and analyzed. We show, in particular, that it is possible to identify some signatures in the quasinormal frequencies from the creation of a naked singularity.
