Binding energy in self-gravitating charged plane symmetric systems

• Gravitational binding energy for charged planar geometry using Taub mass formalism is discussed.
• Non-localized part of the mass function has contribution of electromagnetic field.
• There exist locally bounded systems due to gravitational field.

This paper explores gravitational binding energy in static charged planar spacetime with perfect fluid configuration. We use Darmois formalism to explore the matching conditions of planar symmetry as an interior region and charged Vaidya as an exterior. The mass function is evaluated over the hypersurface to investigate the binding energy in the interior region. We conclude that gravitational field of the planar spacetime binds only the localized part while the non-localized part is due to the electric coupling.
