Contribution

It introduces a relativistic model including thermal pre-relaxation processes and examines the impact of a specific thermodynamic parameter during collapse.

Findings

No anomalous behavior observed at the critical parameter value

The model incorporates thermal pre-relaxation effects

Parameter influences the evolution but remains well-behaved

Abstract

A relativistic model of a heat conducting collapsing star, which includes thermal pre-relaxation processes, is presented. Particular attention is paid to the influence of a given parameter defined in terms of thermodynamic variables, on the outcome of evolution. Evaluation of the system when passing through a critical value of the aforesaid parameter, does not yield evidence of anomalous behaviour.
