When determining a star's surface temperature, what do we need to know? - The peak wavelength of its blackbody spectrum The star Betelgeuse has a lower surface temperature than the Sun; therefore (with IR = infrared and UV = ultraviolet) - Betelgeuse emits more IR and more UV light than the Sun. You are gradually heating a lump of rock in an oven to an extremely high temperature. As it heats up, the lump emits nearly perfect theoretical blackbody radiation, meaning that it - Bluest when h...
