NettetGo to this interactive simulation from the University of Colorado to see the color of a star changing as the temperature is changed.. The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K. Our Sun’s surface temperature is about 6000 K; its peak wavelength color is a slightly greenish-yellow. In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. Conversely, the larger the color index, the more red (or cooler) the object is. This is a consequence … Se mer • Asteroid color indices • Color–color diagram • Distant object color indices • UBV photometric system Se mer • Query for Johnson, H.
