# How do astronomers study the sun's interior?

May 13, 2016

They have computer models of the Sun. This computer model is trying to mimic what would happen in a real star. They start from outside. We know the surface temperature of the sun because it mostly radiates in the yellow, and the Stefan-Boltzman law tells us that the wavelength of maximum emission (the "color") of the surface, is such that ${\lambda}_{\max} T$ is a constant.
