Comment on "Chaotic orbits for spinning particles in Schwarzschild spacetime"

TL;DR

This paper critically examines previous claims of chaos in spinning particles in Schwarzschild spacetime, highlighting theoretical and technical issues in the earlier study.

Contribution

It provides a critical analysis of prior work, identifying key flaws and clarifying the conditions under which chaos may or may not occur.

Findings

Identifies flaws in previous chaos analysis

Clarifies the theoretical framework for spinning particles

Highlights the importance of technical accuracy in chaos detection

Abstract

The astrophysical relevance of chaos for a test particle with spin moving in Schwarzschild spacetime was the objective of \cite{Verhaaren10}. Even if the results of the study seem to be qualitatively in agreement with similar works, the study presented in \cite{Verhaaren10} suffers both from theoretical and technical issues. These issues are discussed in this comment.
