Self-similar scalar field collapse

Understand

A spherically symmetric collapsing scalar field model is discussed with a dissipative fluid which includes a heat flux.

• This vastly general matter distribution is analyzed at the expense of a high degree of symmetry in the space-time, that of conformal flatness and self-similarity.
• Indeed collapsing models terminating into a curvature singularity can be obtained.
• The formation of black holes or the occurrence of naked singularities depends on the initial collapsing profiles.
