Domain walls on the surface of q-stars

Abstract

We study domain-wall networks on the surface of q-stars in asymptotically flat or anti de Sitter spacetime. We provide numerical solutions for the whole phase space of the stable field configurations and find that the mass, radius and particle number of the star is larger but the scalar field, responsible for the formation of the soliton, acquires smaller values when a domain-wall network is entrapped on the star surface.Comment: 11 pages, 6 figures, to appear in Jurn.
