We study angularly excited as well as interacting non-topological solitons, so-called Qballs and their gravitating counterparts, so-called boson stars in 3 + 1 dimensions. Q-balls and boson stars carry a non-vanishing Noether charge and arise as solutions of complex scalar field models in a flat space-time background and coupled minimally to gravity… CONTINUE READING
