Gravitational Collapse of Perfect Fluid
J. F. Villas da Rocha, Anzhong Wang, N. O. Santos
The spherical gravitational collapse of a compact packet consisting of perfect fluid is studied. The spacetime outside the fluid packet is described by the out-going Vaidya radiati…
Instability of cosmological event horizons of nonstatic global cosmic strings II: perturbations of gravitational waves and massless scalar field
José A. C. Nogales, Anzhong Wang
The stability of the cosmological event horizons (CEHs) of a class of non-static global cosmic strings is studied against perturbations of gravitational waves and massless scalar f…
Generalized Vaidya Solutions
Anzhong Wang, Yumei Wu
A large family of solutions, representing, in general, spherically symmetric Type II fluid, is presented, which includes most of the known solutions to the Einstein field equations…
Spherical Self-Similar Solutions in Einstein-Multi-Scalar Gravity
Eric W. Hirschmann, Anzhong Wang
We consider a general non-linear sigma model coupled to Einstein gravity and show that in spherical symmetry and for a simple realization of self-similarity, the spacetime can be c…
