It presents new exact solutions for non-spherical scalar field collapse, including planar, toroidal, cylindrical, and pseudoplanar symmetries, highlighting collapse possibilities with dark energy equations.

Findings

Scalar fields can collapse under non-spherical symmetries.

Collapse occurs even with dark energy-like equations of state.

Various symmetry models exhibit collapse modes.

Abstract

In the present work the collapse scenario of some exact non-spherical models with a minimally coupled scalar field is studied. Scalar field collapse with planar as well as toroidal, cylindrical and pseudoplanar symmetries have been investigated. It is shown that the scalar field may have collapsing modes even if it has the equation of state corresponding to that of a dark energy.
