And no, I am not talking gibberish. This aint no slander. This is how stars are 'rated'.
Stars, like we speculated, are in fact classified based on their spectra and temperature.
Lets say,the colour of the star is based on the temperature. The temperature on the star decides what elements are present. The elements present shall absorb/emit radiations. These elements are determined by analysing the spectrum. The width of the spectrum decides the classification.
The spectral classes are O B A N G K M. And the first line of this post is a mnemonic to remember this. Take a look at this data courtesy the http://www.tutornext.com.
There is a chart called the Hertzsprung - Russell diagram. On this the stars are marked based on Spectral type, surface temperature, luminosity and absolute magnitude.
