Remarks about the thermodynamics of astrophysical systems in mutual interaction and related notions

TL;DR

This paper discusses the thermodynamics of interacting astrophysical systems, clarifying misconceptions and emphasizing the differences from traditional thermodynamics of extensive, short-range systems.

Contribution

It provides a critical analysis of the thermodynamics of open astrophysical systems and addresses misconceptions in applying classical frameworks to these large, long-range interacting systems.

Findings

Highlights differences between astrophysical and classical thermodynamics

Clarifies misconceptions about applying extensive system theories to astrophysics

Emphasizes the importance of long-range interactions in astrophysical thermodynamics

Abstract

General aspects about the thermodynamics of astrophysical systems are discussed, overall, those concerning to astrophysical systems in mutual interaction (or the called \emph{open astrophysical systems}). A special interest is devoted along the paper to clarify several misconceptions that are still common in the recent literature, such as the direct application to the astrophysical scenario of notions and theoretical frameworks that were originally conceived to deal with extensive systems of the everyday practice (large systems with short-range interactions).
