Empirical Modelling and Thermal Structure of Sunspots
Abstract
An overview of empirical models of sunspot thermal structure is presented. First a few remarks are made on empirical modelling in general. After that the literature on the various types of models, 1- and 2-component models of the umbra and penumbra, is reviewed. The evidence for or against the dependence of umbral temperature on various parameters like sunspot size, magnetic field strength and phase of the solar cycle is critically reviewed.
