摘要

Static solutions in spherical symmetry are found for gravitating global monopoles. Regular solutions lacking a horizon are found for η<1/8π\eta < 1/\sqrt{8\pi}, where η\eta is the scale of symmetry breaking. Apparently regular solutions with a horizon are found for 1/8πη\alt3/8π1/\sqrt{8\pi} \le \eta \alt \sqrt{3/8\pi}. Though they have a horizon, they are not Schwarzschild. The solution for η=1/8π\eta = 1/\sqrt{8\pi} is argued to have a horizon at infinity. The failure to find static solutions for η>3/8π0.3455\eta > \sqrt{3/8\pi} \approx 0.3455 is consistent with findings that topological inflation begins at η0.33\eta \approx 0.33.
