WebThe corresponding color indices are B - V = 0.7 - 0.9 = - 0.2 U - B = -0.24 -0.7 = - 0.94 Generally, the negative values of these color indices are an indication that Spica is a hot star, with most of its radiation coming at shorter wavelengths. On the other hand, for Antares B = 2.7 and V=0.9, and the B - V color index is B - V = 2.7 - 0.9 = 1.8 WebGo 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.

WebThe intensity of radiation emitted by the sun has its maximum value at a wavelength of 510 nm and that emitted by the north star has the maximum value at 350 nm. If these stars … WebThe colour of the star is an indication of its temperature. The glowing is caused by something called black−body radiation . Which has to do with the heat energy trying to radiate away in more and more energetic wavelengths. Red stars are relatively cool at only a few thousand degree Celsius. While stars are hot at about ten thousand degrees ... WebThe colour of a star is an indication of its _____. A. distance from the sun. B. luminosity. C. distance from the earth. D. temperature.
