What color a star us based on the stars surface temperature?

Answer 1

Yes the color of a star does afect the temp. of a star Blue stars such as Sirus B are the hottest, stars such as Polaris (AKA the North Star) are cooler than the blue ones. Also, stars such as that are yellow-white such as the sun are medium temp.

Answer 2

It tells them what the temperature is. There's an equation that gives the spectral curve for an object (a "black body") that is glowing due to its own temperature rather than reflecting light emitted by some other object, and this curve is different at every temperature. Very roughly speaking, "cool" (for stars) stars appear red, and as they get hotter they turn orange, yellow, yellowish-white, white, bluish-white, and finally blue. The actual spectrum (or at least the wavelength of the spectral maximum) is needed to determine the temperature precisely, but you can make some guesses just by what color the star seems to be to your eye.

Correct for red shift

Answer 3

Stars can be small, medium, or large. Their color and temperature depends on their size. Not a long answer but a science teacher should know.

Answer 4

The stars temperature will be greater than 30,000 K

Answer 5

Yes, that is correct. The color basically depends on the temperature of the star's visible part.
