Abstract: (arXiv)
Cosmic balloons are spherical domain walls with relativistic particles trapped inside. They could be created in the early Universe and of much astrophysical interest. Here we find a transparent analytical approximation for the mass density of a spherically symmetric relativistic gas star. When applied to the computation of the mass and radius of a cosmic balloon, the analytical approximation yields fairly good agreement with the exact numerical solutions. The cosmic balloon mass as a function of its radius, , is found to have a spiral behavior similar to that of fermion soliton stars, with a fixed point at , which corresponds to the limit of infinite central density.Note:
