The Final State of the Thermal Evolution of Free-Floating Giant Planet

TL;DR

This paper explores the thermal evolution of free-floating giant planets, proposing that their final state involves the existence of superconducting metallic hydrogen within cold giant planets.

Contribution

It introduces the concept that cold free-floating giant planets reach a final state characterized by superconducting metallic hydrogen, advancing understanding of their thermal evolution.

Findings

Cold giant planets contain superconducting metallic hydrogen.

The final state of thermal evolution is a cold, superconducting phase.

Superconductivity plays a key role in the planet's thermal properties.

Abstract

In the paper, we have discussed the problem of the existence of the metallic hydrogen in the superconducting state inside the cold giant planet. We have shown that the {\it cold} planet represents the final state of the thermal evolution of free-floating giant planet.
