We have shown previously that in the case of a perfect fluid, only the localized part of the mass contributes to gravitational self-binding of such objects and that in the limiting case of objects comprised purely of electromagnetic mass, there is no gravitational binding. Here, we extend this result to the more general case of an anisotropic fluid. Our inspection of the Oppenheimer–Volkov equation allows tracking of both gravitational and non-gravitational contributions to binding of spherically symmetric objects and shows that those with pure electromagnetic mass cannot exist.}, number={9}, journal={INTERNATIONAL JOURNAL OF THEORETICAL PHYSICS}, author={Corne, Matthew and Kheyfets, Arkady and Piasio, Jennifer and Voegele, Chad}, year={2011}, month={Sep}, pages={2737–2747} }

Here, we consider a static, spherically symmetric object consisting of a charged perfect fluid. For this object, the total gravitational mass contains a non-localizable contribution of electric coupling (ordinarily associated with electromagnetic mass). We derive an explicit expression for the total mass which implies that the non-localizable contribution of electric coupling is not bound together by gravity, thus ruling out the existence of objects with pure Lorentz electromagnetic mass in general relativity.}, number={23}, journal={CLASSICAL AND QUANTUM GRAVITY}, author={Corne, Matthew and Kheyfets, Arkady and Miller, Warner A.}, year={2007}, month={Dec}, pages={5999–6005} }
