Starspot temperature
Abstract
The results of modern studies of the properties of spots on the surfaces of stars of late spectral classes are considered. The new data indicates a significant difference with an average previously constructed dependence based on the compilation data. According to the corrected dependence, the temperature difference ΔT between the spots and the photosphere decreases from approximately 1000 K for G0 stars to 200 K for M4 stars. Thus, the value of ΔT should be for solar-type stars lower by 1000 K than was previously assumed but remained unchanged for M dwarfs.
