Causal temperature profiles in horizon-free collapse
N F Naidu, M Govender
TL;DR
This paper analyzes the temperature distribution in a horizon-free collapsing star model, demonstrating that the model produces physically reasonable temperature profiles consistent with extended irreversible thermodynamics.
Contribution
It introduces a simple exact model of radiating star collapse without horizon formation, providing insights into temperature behavior during such collapse.
Findings
Temperature profiles are physically reasonable within the model.
The model aligns with extended irreversible thermodynamics.
Collapse occurs without horizon formation, challenging traditional views.
Abstract
We investigate the causal temperature profiles in a recent model of a radiating star undergoing dissipative gravitational collapse without the formation of an horizon. It is shown that this simple exact model provides a physically reasonable behaviour for the temperature profile within the framework of extended irreversible thermodynamics.
