Abstract
The discovery of potentially habitable Earth-like exoplanets orbiting around hosting stars increased the interest in investigating their climate systems. In this perspective, we study the stability properties of a simple energy balance climate-vegetation model. It describes the interaction between the planetary surface, that can be partially covered by vegetation, a large ocean and a land surface. The model allows to investigate changes in response to variations in the hosting star’s irradiance (e.g. due to mutual distance variations). The stability properties of the system change according to variations of the control parameters, as for example the effective growth rate of vegetation γ and the stellar distance a. In particular, the model presents both stable and unstable fixed points, which can exhibit several kinds of stability properties depending on the distance of the planet from the hosting star.
Highlights
A complete description of the Earth’s climate system in terms of the full set of atmospheric variables is quite complex, due to their variability on several timescales [1,2,3,4,5,6]
Energy Balance Models (EBMs) allow to explore a large set of variables inside the parameter space and, in particular, they include the effects of vegetation that distinguishes them from the more complex and complete general circulation models (GCMs)
The Daisyworld-like model considered in this work describes an Earth-like planet covered by land and ocean, with the possible presence of vegetation
Summary
Any further distribution of The discovery of potentially habitable Earth-like exoplanets orbiting around hosting stars increased this work must maintain the interest in investigating their climate systems. In this perspective, we study the stability properties attribution to the author(s) and the title of of a simple energy balance climate-vegetation model. We study the stability properties attribution to the author(s) and the title of of a simple energy balance climate-vegetation model It describes the interaction between the the work, journal citation and DOI. The model allows to investigate changes in response to variations in the hosting star’s irradiance (e.g. due to mutual distance variations).
