Many-body aspects of gravity in compact stars

Compact stars, such as neutron stars and black holes, are gravitationally bound many-body systems. We investigate the importance of short- and long-range part of gravity for such systems. From our analysis, we conclude that the true essence of gravity lies with the long-range nature of the interaction. At the end of this paper, we show how these arguments in the many-body theory consistently leads to Dvali-Gomez picture of a black holes as a collective bound state of long wavelength gravitons.
