i really o not understand the significance of the question that is asking
The light that comes from the star. The light is spread out into its spectrum and the pattern of spectral lines allow the composition (and temperature) to be determined. The temp can also be found by looking at the black body curve for the star (also from spectrum), or, by looking at the color of the star (difference in intensity of the light through two different color filters typically B and V.

the astromers of babylon mapped the stars and the plants
Aratus knew quiet a bit about the stars. He was able ( through his writings ) to give the location of all the constalations he knew of. I guess he struck other astronomers for his knowledge about the stars: knowledge it took them a while to gain.
All serious astronomers realize that there are binary stars.

Astronomers classify stars.
Spectral analysis.
To compare and classify stars.
For one reason, astronomers can figure out what stars are composed of by looking at their spectral lines.
spectral analysis
spectral analysis
The composition is determined by spectral analysis.

Classify stars and to understand how stars change over time
The H-R diagram compares a star's surface temperature to its absolute brightness.
spectral analysis of light of stars help us
