On compactness limit of a charged object in general relativity
Prof. Naresh Dadhich
Inter-University Center for Astronomy & Astrophysics, Pune, India

A very general and novel prescription for compactness of a static object/star would be proposed. The compactness limit is defined when gravitational field energy exterior to object is less than or equal to half of its non-gravitational energy for a charged object described by the unique Reissner-Nordström electrovac solution of the Einstein equation. This definition makes no reference to the interior at all, may what that be. (arxiv:1903.03436)
