* Temperature and Color: The color of a star is directly related to its surface temperature. Hotter stars emit more blue light, while cooler stars emit more red light.
* Blackbody Radiation: Stars, like all objects, emit radiation according to their temperature. This is known as blackbody radiation. The peak wavelength of the radiation emitted shifts towards shorter wavelengths (bluer light) as the temperature increases.
* Stellar Classification: Stars are classified based on their spectral type, which is related to their temperature. The hottest stars are classified as O and B stars, and they appear blue-white. Red stars are classified as M stars and are much cooler.
So, while red stars might seem "hot" because they emit some light, they are actually the coolest stars we can see.
