Description
Non-topological solitons, of which Q-Balls are particular examples, are localised solutions in field theories which have finite energies. Q-Balls were first explored by Sidney Coleman back in 1985, and then extensively studied by others. Due to the non linearity in the equations of motion, it is very difficult to obtain analytical solution except in some limiting cases (thin and thick wall limit). Recently there has been a resurgence in the study of Q-Balls, initiated by the discovery of certain novel methods to obtain analytical solutions. We study in detail the astrophysical implications if such objects were to form Exotic Compact Objects (ECOs). We have derived previously unknown bounds and observational signatures for such objects.
