Charged black-bounce spacetimes

Abstract Given the recent development of rotating black-bounce-Kerr spacetimes, for both theoretical and observational purposes it becomes interesting to see whether might be possible construct black-bounce variants entire Kerr-Newman family. Specifically, herein we shall consider black-bounce-Reissner-Nordström black-bounce-Kerr-Newman spacetimes as particularly simple clean everywhere-regular black hole “mimickers” that deviate from family in a precisely controlled minimal manner, smoothly interpolate between regular holes traversable wormholes. While observationally electric charges on astrophysical are likely extremely low, | Q |/ m ? 1, introducing any non-zero charge has significant impact. In particular, verify existence Killing tensor (and associated Carter-like constant) but without full tower principal Killing-Yano tensor, also discuss how, assuming general relativity, solution requires an interesting, non-trivial matter/energy content.
