Abstract This work seeks to summarize some special aspects of a type of exoplanets known as super-Earths (SE), and the direct influence of these aspects in their habitability. Physical processes like the internal thermal evolution and the generation of a protective Planetary Magnetic Field (PMF) are directly related with habitability. Other aspects such as rotation and the formation of a solid core are fundamental when analyzing the possibilities that a SE would have to be habitable. This work analyzes the fundamental theoretical aspects on which the models of thermal evolution and the scaling laws of the planetary dynamos are based. These theoretical aspects allow to develop models of the magnetic evolution of the planets and the role played by the PMF in the protection of the atmosphere and the habitability of the planet.

超级地球中的行星磁场和宜居性

摘要 这项工作旨在总结一种被称为超级地球 (SE) 的系外行星的一些特殊方面,以及这些方面对其宜居性的直接影响。内部热演化和保护性行星磁场 (PMF) 的产生等物理过程与宜居性直接相关。在分析 SE 必须适合居住的可能性时,其他方面(例如旋转和固体核心的形成)是基础。这项工作分析了热演化模型和行星发电机的标度定律所基于的基本理论方面。这些理论方面允许开发行星磁演化模型以及 PMF 在保护大气和行星宜居性方面所起的作用。
