How do they measure the core temperature of the sun?

Can't actually measure it since we don't have instruments that can withstand that type of heat. However, we can infer the core temperature by applying physical principles to other measurements. We can determine that mass, volume, composition, etc. of the sun and based off of this information and certain assumptions we can calculate what the core temperature should be.
