Tell me the relationship between stars and their color?

Question

Also tell me the differnt kinds of stars and give me a brief description.

Thanks

Answer 1

A good question and it has an answer. By Wien's Law the wavelength of maximum emission is inversely proportional to the temperature of the radiating body. Therefore the higher the temperature of the star's surface the lower the wavelength of maximum emission of the star, which means the wavelength will move toward the blue end of the visible spectrum. The hottest stars are blue, the least hottest are red in appearance. Wien's Law is: W (normally the Greek letter lambda) = 2897/T where T is in degrees Kelvin.

Answer 2

I believe they're direct relationships. The higher the surface temperature, the farther up the ladder the spectral type goes, from type M to type O. Also, the color of the star is directly related to its surface temperature, beginning from red, to orange, to yellow, to yellow-white, to white, to blue-white, and then to blue. The actual mass of a star and its age can play a huge difference in the surface temperature of a star, but the spectral type and color of a star are dependent solely on its surface temperature.

Answer 3

When I see a star the relationship lies in time travel.You realize the star you are viewing is giving a glimpse back in time million of years.Yep,it takes the light from a star many a long time to get here,reach us.

Answer 4

The larger the star the bluer it is. A larger star burns hotter, since blue is a shorter wavelength it can carry more energy.

Smaller stars are yellower and burn cooler.
