An Informational–Entropic Approach to Exoplanet Characterization [PDF]
In the past, measures of the “Earth-likeness” of exoplanets have been qualitative, considering an abiotic Earth, or requiring discretionary choices of what parameters make a planet Earth-like.

Lévy noise versus Gaussian-noise-induced transitions in the Ghil–Sellers energy balance model [PDF]
We study the impact of applying stochastic forcing to the Ghil–Sellers energy balance climate model in the form of a fluctuating solar irradiance. Through numerical simulations, we explore the noise-induced transitions between the competing warm and ...
